I have migrated my SIGPro over to my host (I was selfhosting on the MAMP server previously).
After looking through the forum I changed my folders so now my
Cache Folder = 775
Image Folders = 777
There was no Temp folder in my Joomla Images folder.
I did change permissions on the
tmp folder = 777 that was in Joomla.
My images all have the 644 permission on them and jpg is lower case.
When I click on the thumbnail box the image shows up just as it should.
Here's a link to one of my problem areas www.artransforms.com/joomla15/index.php?option=com_content&view=category&layout=blog&id=7&Itemid=5

You have permissions issue and you must console your hosting company.
Check by yourself too by trying accessing this image of your gallery:

www.artransforms.com/joomla15/cache/jwsigpro_cache_f105048806allsides.gif

The link doesn't work because it should be .jpg instead of .gif . I'm not sure how you got that link but if you change the link to .jpg it works just fine.

I took it from the source code of your site... So please check your images names...

I am using the Simple Image Gallery Pro v2 and it works fine in our template. Recently I found another plugin which causes some problems with the gallery.
The plugin is Joomla Imagesized Plugin.

Using this plugin causes the thumbnail boxes in the gallery to become empty.

I was wondering if there is a fix for this problem?

Please provide me with a link to your site.

Can you please let me know where you found this source code on my site, because as far as I can tell my image names match up w/ the files. In my cache folder all the images are .jpg, matching the file names for the photos.
This would be very helpful to me, so I can check out what you are talking about/ see where the discrepancy might be coming from.

Sorry, currently we are running locally and can not upload the site as yet. I put down the plugin name just in case it was possible for you to use the combination of the two extensions to see if there is a problem.
Extension:
Joomla Imagesized Plugin
extensions.joomla.org/extensions/news-display/articles-summary/5738
Simple Image Gallery PRO plugin which I purchased from JoomlaWorks.

Currently I can not grant access to the site.

Your help would be greatly appreciated.

@Hobbesfrnd,
Go to your page with SIG PRO and check the View Source Code (Ctrl+U). At line 186 you will see the link I have posted you above...

@Teru, try to change pop up engine at SIG Pro. If this doesn't solve the problem... you must choose between the two plugins...

Fixed the issue:

Changed the settings in the Joomla Imagesized Plugin
Sized image in Article : change to No

I checked my page with sigPro and they were all .gif the same as the images. I "fixed"(not really) the problem by transferring over all my old files from when I was self hosting it over onto the hosted account, however I just discovered it didn't fully work. I'm stumped. Through doing troubleshooting I have come upon the same issue. If you look at this page www.artransforms.com/joomla15/index.php?option=com_content&view=category&layout=blog&id=8&Itemid=6  I have two of the exact same files one that I imported over (with all my other files) onto my hosted site where the preview images are showing. The other the exact same file ftp'ed over (with an extra letter in the file name) . They have the exact same pictures, the exact same file access and yet one has thumbnail images and the other does not. I really need some help with this.

Do you see the difference between preview_gallery and ppreview_gallery?

That's accurate because that's the second folder name. The only difference between the two folders with images in them is that one has an extra p in preview. That is, unfortunately, not a typo but something I did on purpose.

I'm thinking that perhaps I need a fresh version of Simple Gallery Pro to download as I can see any problems with my files/ permissions etc. but I got some of the galleries to work by copying over all my files. Do you know how I could go about getting a fresh download copy of SIGPro? Or do you have another solution that I don't see?

You may access PDS (top menu of joomlaworks.net) in order to redownload the plugin and reinstall it...

Hi all, just to let you know if you've tried all of the above and you still have this problem. Check with your host to see what version of PHP you are running.

Hi, I just wanted to let you know what the issue was. I believe (at least for SIG Pro for Joomla 1.5) that my PHP version was not as current as it should have been. The documentation says PHP 4 works but, honestly, my site was running on 4.3 (from 2002) and as soon as I switched everything to another host with a more current PHP and had no problems with it whatsoever.
