Using SIG Pro, I set the base path to /images/stories/mystuff - fine
BUT when I use K2->image gallery tab to upload ZIP file the images go to media/k2/galleries - not so good
How do I change this??

Also, since the upload automatically creates a new folder with the name of the K2 item id I will need to always use
{gallery}#k2itemid{/gallery} to show the gallery
Since I don't know the itemid until after I save the K2 item can I use a 'generic' tag for every K2 item

Example {gallery}%ID%{/gallery}

I'm using SIG Pro to put image galleries into K2 items. All is working fine- but I would like to be able to set it up so that my clients can easily write captions. Which is to say that they could easily access the file that SIG Pro makes for captions and stores in the same dir as the image gallery.

K2 uploads the images into media/k2/galleries, and seems to override whatever path I write into the SIG Pro pluging params. K2's beautiful(!) media manager root dir is /images and can't access /media.

If I could either change the dir where K2 stores galleries to something in /images- or change the root dir of the media manager- maybe to site root- so the image gallery directories are accessible in the media manager, I think that would do the trick.

Can either of these be done? And which would be better?

Thanks so much!

After a couple of my questions beeing unanswered I try another way of Heading my Topic ;)

I think the question is for "advanced" User, maybe someone can Help me.

I am using Joomla 1.7.2 with Joomlart T3 Framework and K2 v 2.5.1 and I have a Problem with the mod_K2_user render Module Function.

As I tried to use it with K2 v. 2.5 I had an Issue with white modal and pop-up screen as I set the link to Item_Edit_K2_Link to Menu. The Problem with white page is still happening even after Update to 2.5.1 where Joomlaworks says they fixed it. But the Error Code has changed.

Issue in K2 2.5

Is it possible to add a Joomla content plugin to the item.php page? What I did was install the Simple Picture Slideshow plugin:
extensions.joomla.org/extensions/photos-a-images/images-slideshow/6432

I changed the image root path to: /media/k2/galleries/

In my item.php page I inserted the plugin code:
{besps}<?php echo $this->item->id; ?>{/besps}

This pulls the respective item's ID correctly but the plugin in not rendered, such as if my K2 item is 92 it shows:
{besps}92{/besps}


Thank you,
Wesley

You see the same image because the image file is still the same and the browser thinks it's still the same image. Of course this doesn't happen forever. It depends on the browser and could take up to a few minutes for it to recognize the changed image, through the image's headers sent...

Anyway, since this was a problem high-traffic sites dealt with, we added this new option in the K2 parameters (in v2.5.0), which attached the item modified date to the name of the image file, thus forcing the browser to fetch the changed image.

In the backend, open the K2 parameters, switch to the "Images" tab, set "Force 'item modified date' as URL timestamp on image paths" to "Yes". Save.

Now you won't see this issue again.

Something else. All thumbs in Admin side (Image Gallery tab) are now just text. Maybe it is intentional, but all images and link under them got in path "administrator".

You can change it in Joomla Global Configuration ----&gt; Media Settings ----&gt; Path to Media Folder

But you change then for whole Joomla (editor too),i believe.

 

Try to do something with this hack, if Global Settnigs doesn´t suit you:

community.getk2.org/forum/topics/k2-item-edit-hack-to-show-just

In the item editing window when you click Browse Server on the Image tab it takes you to the default images folder set in Global Configurations in Joomla! so you see all the folders on the server. I didn't want the user to be able to select another user's content, so after a good deal of sleuthing I came up with this hack:

Open the administrator/components/com_k2/views/item/tmpl/filebrowser.php

On about line 12, under the restricted access and within the PHP tags put this to grab the user id:

$user =&amp; JFactory::getUser();$userid=$user-&gt;id;

 

Then at around line 32, under if(count($this-&gt;folders)): and still within the php tags put:

  if($this-&gt;path==$this-&gt;parent){//root folder of the images path            $this-&gt;folders=array($userid);//reduce folder array to just the user's folder   }

What it does is see if you are at the root images path and, if so, the folder array is changed so it contains only the user's folder.

Hi,

I have found that the plugin is not using flv but flvremote even when the video is on your website. So, to get the preview image to display I have made the following changes to the plugin version 3.3.

Backup the two files below, before you make the changes so you can fall back to a working copy if anything goes wrong.

In /plugins/content/jw_allvideos.php:
Around line 162 you will find this code:
Change it to:
Find this code:
Replace it with this code:
Find this code:
Replace it with this code:
Finally in /plugins/content/jw_allvideos/includes/sources.php on line 39 in the flvremote section replace:
with:
Making these changes should now give you a preview images as long as you have the image in the same folder as your flv file and you name the image file the same as the flv file, but with a .jpg extension. If you wanted a different extension on your image file change it in the line above (.jpg for .png, if you wanted png images instead).

To get the image to display properly in K2 you need to add the following hack to remove the beginning / from the video path:

/administrator/components/com_k2/views/item/tmpl/fielbrowser.php line 42 remove the beginning / from the <a href="
becomes:


I hope this helps others get their preview image for flv files.

Good luck.

To the category_item.php (override K2 template first, if not already), locate the catItemImageBlock.

 

&lt;?php if($this-&gt;item-&gt;params-&gt;get('catItemImage') &amp;&amp; !empty($this-&gt;item-&gt;image)): ?&gt;            &lt;!-- Item Image --&gt;            &lt;div class="catItemImageBlock"&gt;                &lt;span class="catItemImage"&gt;                    &lt;a href="&lt;?php echo $this-&gt;item-&gt;link; ?&gt;" title="&lt;?php if(!empty($this-&gt;item-&gt;image_caption)) echo $this-&gt;item-&gt;image_caption; else echo $this-&gt;item-&gt;title; ?&gt;"&gt;                        &lt;img src="&lt;?php echo $this-&gt;item-&gt;image; ?&gt;" alt="&lt;?php if(!empty($this-&gt;item-&gt;image_caption)) echo $this-&gt;item-&gt;image_caption; else echo $this-&gt;item-&gt;title; ?&gt;" style="width:&lt;?php echo $this-&gt;item-&gt;imageWidth; ?&gt;px; height:auto;" /&gt;                    &lt;/a&gt;                &lt;/span&gt;            &lt;div class="clr"&gt;&lt;/div&gt;            &lt;/div&gt;&lt;?php endif; ?&gt;

 

You can make a change to that statement and load the default image you want when there is no Image present. It shouls look like this:

 

&lt;?php if($this-&gt;item-&gt;params-&gt;get('catItemImage') &amp;&amp; !empty($this-&gt;item-&gt;image)): ?&gt;             &lt;!-- Item Image --&gt;             &lt;div class="catItemImageBlock"&gt;                 &lt;span class="catItemImage"&gt;                     &lt;a href="&lt;?php echo $this-&gt;item-&gt;link; ?&gt;" title="&lt;?php if(!empty($this-&gt;item-&gt;image_caption)) echo $this-&gt;item-&gt;image_caption; else echo $this-&gt;item-&gt;title; ?&gt;"&gt;                         &lt;img src="&lt;?php echo $this-&gt;item-&gt;image; ?&gt;" alt="&lt;?php if(!empty($this-&gt;item-&gt;image_caption)) echo $this-&gt;item-&gt;image_caption; else echo $this-&gt;item-&gt;title; ?&gt;" style="width:&lt;?php echo $this-&gt;item-&gt;imageWidth; ?&gt;px; height:auto;" /&gt;                     &lt;/a&gt;                 &lt;/span&gt;             &lt;div class="clr"&gt;&lt;/div&gt;             &lt;/div&gt;

&lt;?php else : ?&gt;

&lt;div class="catItemImageBlock"&gt;                 &lt;span class="catItemImage"&gt;                     &lt;a href="&lt;?php echo $this-&gt;item-&gt;link; ?&gt;" title="&lt;?php echo $this-&gt;item-&gt;title; ?&gt;"&gt;                         &lt;img src="YOUR_IMAGE_SOURCE" alt=""  /&gt;                     &lt;/a&gt;                 &lt;/span&gt;             &lt;div class="clr"&gt;&lt;/div&gt;             &lt;/div&gt;

&lt;?php endif; ?&gt;

 

Put your default image to the template images or wherever you want and put the path to the src of the img.

Don't understand what you mean by the last stage. i have followed on a local host install and it seems to be creating a png and a jpg and still picking the converted png.(this is in the cache folder.)

So how do I get it to recognise the png.

Finally, wherever you are using an image from the k2 item, replace the .jpg extension with .png (if you need transparancy).

In short, technique writes an additional set of png (alpha intact) to the cache directory, and makes them available to the application via the same name as the jpg counterpart. No existing functionality should be broken by this since it is an additive change. I'll post a more thorough blog about this at some point.

One final note, if you need to implement the png version, a simple string replace looks something like this:


I'm a c# guy, not really php, and being as lazy as I am, I'm not going to look up how to do a proper substring trim... just dont name your image blah.png.png.png....
Good Luck!

Hi all, 

First the disclaimer, I do not consider myself a professional programmer in any sense, more the stubborn trial-and-error kind of guy. Anyhow, this filename thing was really bugging me, mainly for SEO purposes. 

So I dug around some in the code. I usually try to avoid hacks as they can cause trouble at upgrades, but if you want to try the below it did what I wanted it to do for me. As usual, make back-ups of the files below before starting in case you mess up and need to revert.

So, enough with the disclaimers, here it goes (my K2 version by the way 2.4.1).

The basis for the whole thing is that I do not use the field Image Credits (found in K2 Item Editor -&gt; Image) for anything, so decided to use that for file naming purposes. Also I do not have the lightbox function activated so I have not tested if that works with this hack.

1. in administrator/components/com_k2/models/item.php

Line 207, change to:

$handle-&gt;file_new_name_body = $row-&gt;image_credits;

2. components/com_k2/models/item.php

Starting on line 110, add the line:

$myfilename = $item-&gt;image_credits;

Then there are the following 16 lines below that which need to be modified to:

if (JFile::exists(JPATH_SITE.DS.'media'.DS.'k2'.DS.'items'.DS.'cache'.DS.$myfilename.'_XS.jpg')) $item-&gt;imageXSmall = JURI::root().'media/k2/items/cache/'.$myfilename.'_XS.jpg'; if (JFile::exists(JPATH_SITE.DS.'media'.DS.'k2'.DS.'items'.DS.'cache'.DS.$myfilename.'_S.jpg')) $item-&gt;imageSmall = JURI::root().'media/k2/items/cache/'.$myfilename.'_S.jpg'; if (JFile::exists(JPATH_SITE.DS.'media'.DS.'k2'.DS.'items'.DS.'cache'.DS.$myfilename.'_M.jpg')) $item-&gt;imageMedium = JURI::root().'media/k2/items/cache/'.$myfilename.'_M.jpg'; if (JFile::exists(JPATH_SITE.DS.'media'.DS.'k2'.DS.'items'.DS.'cache'.DS.$myfilename.'_L.jpg')) $item-&gt;imageLarge = JURI::root().'media/k2/items/cache/'.$myfilename.'_L.jpg'; if (JFile::exists(JPATH_SITE.DS.'media'.DS.'k2'.DS.'items'.DS.'cache'.DS.$myfilename.'_XL.jpg')) $item-&gt;imageXLarge = JURI::root().'media/k2/items/cache/'.$myfilename.'_XL.jpg'; if (JFile::exists(JPATH_SITE.DS.'media'.DS.'k2'.DS.'items'.DS.'cache'.DS.$myfilename.'_Generic.jpg')) $item-&gt;imageGeneric = JURI::root().'media/k2/items/cache/'.$myfilename.'_Generic.jpg'; 

3. When uploading a new file in the K2 Editor under Items -&gt; Image in the backend, just make sure to put your filename in the "Item image credits" field (without any .jpg), for example: my_pretty_seo_image

Note: When I started this work I had not yet uploaded any images, so during testing I went in via FTP and erased all image files under media/k2/items/cache/, so I do not know how it works with overwriting existing images.

Now I am a bit mentally exhausted and in need of lunch so I might have forgotten some modification I made, but I hope the above is of some help to you.

For those wanting to use Rokstories, there is one final edit to make.  From the RT forums:

You need to edit modules/mod_rokstories/helper.php at lines 273 and 274


        if (file_exists(JPATH_SITE.DS.'media'.DS.'k2'.DS.'items'.DS.'cache'.DS.md5("Image".$id).'_'.$image_size.'.jpg')) {
            $image_path = 'media/k2/items/cache/'.md5("Image".$id).'_'.$image_size.'.jpg';
            $images-&gt;image = JURI::Root(true).'/'.$image_path;
 




Just change the .jpg to .png.

I'm not seeing Generic image processing around line 295?  Running K2 2.4.1.

I've got a solution for this. its not super sexy, but it works.
in /components/com_k2/models/item.php replace the if chain starting on line 110 with:

Finally, wherever you are using an image from the k2 item, replace the .jpg extension with .png (if you need transparancy).

In short, technique writes an additional set of png (alpha intact) to the cache directory, and makes them available to the application via the same name as the jpg counterpart. No existing functionality should be broken by this since it is an additive change. I'll post a more thorough blog about this at some point.

One final note, if you need to implement the png version, a simple string replace looks something like this:


I'm a c# guy, not really php, and being as lazy as I am, I'm not going to look up how to do a proper substring trim... just dont name your image blah.png.png.png....
Good Luck!

In my first reply .. i said :

I copied the images folders to :
- my template/html/com_k2/images
- my template/images
- root/images

I tried several ways ...

the only difference is that i changed the movies output to "after text full form"

the website is still over development...but the url in question is www.unione.art.br/portal/index.php?option=com_k2&view=item&id=35:swu-entrevista-juliana-wallauer&Itemid=23

Others K2 templates is "still" OK ...

ok .. i will tell you what i did :

The structure is :
mytemplate/html/com_k2/
/templates/totallnet/item.php
/templates/totallnet/item_comments_form.php
/templates/totallnet/latest.php
/templates/totallnet/latest_item.php
/templates/totallnet/category.php
/templates/totallnet/category_item.php
/templates/totallnet/category_item_links.php
/templates/totallnet/images/fugue/
/templates/totallnet/images/placeholder/
/templates/totallnet/images/social/
/templates/totallnet/images/system/

Off course all the images are in their respective folders...

The changed that i had made :

In item.php we need that the video appear into the text field and not after text field... so... copy the lines above and put after :

























Its the wrong way ??? .. may i do somothing or everything wrong ??

Ps im not developer.. off course you see my inexperience .. but im a novice joomlas enthusiastics

Hi Simon,I pay for fix my issue with Gallery in K2 item Page. I need it asap. Where i find out a K2 expert ?Maybe you can help me in this matter. I am really desperate!Despite a lot of changes and follow many tips &amp; tricks from K2 forums, I still no getting any galleries in my items page.The
zip file upload is fine and I can see my images in media/k2/galleries by FTP, my SIG version  is PRO 2.0.5 with correct path to media/k2/galleries.No error message I get, I can't see gallery thumbs in item page. My Joomla is 1.5.21 and PHP 5.2.14NOTE:
If I disable SIG PRO I can see in item page the gallery tag like &lt;gallery&gt;1&lt;/gallery&gt; what means SIG Pro is disable of course, but working therefore. When activated again the tag disappears and the Gallery isn't showed as before.thanks for any help,pablobr
