Yeah. Thanks. I think about that. And also, its better to store images into seperate folders, to prevent max listing (e.g. 1000 images in 6 sizes are 6000 images).
olsen said:You can just resize and rebuild cache uploading again all images. Yeah, we know all that this is not the best way that how K2 should work but by now its how K2 is desing it.
What it can be done, if somebody wants to resize images without uploading them again, is get under cachefolder->size to resize all images, and change width, through any image software and then upload them again to the same folder.

Well, finally i've created a patch to allow image cache reconstruction from sources using current image size parameters. You must open the file items.php (into the models folder of frontpage component). Locate the function prepareItem and then into this function, locate the following lines:
replace those lines with this code:
and finally at the end of class K2ModelItem (just before the last } ) add this new function:
That's all, i hope that you enjoy the new function!! Now if you delete some or all images from the cache folder, they are rebuilded from their sources (using the new size if it has changed). It works fine for me...

}That's all, i hope that you enjoy the new function!! Now if you delete some or all images from the cache folder, they are rebuilded from their sources (using the new size if it has changed). It works fine for me...

I'm going to try this too, but I have a followup question: Is there a way to modify the image processing script to keep the original file name (instead of changing it to ffee2447b152494b43d9816faaea83c8_Generic.jpg)? It'd be easier to track my files if the image is renamed to picture_Generic.jpg.
This would help my site development by allowing me to upload and work with the images I think I need, but later go back and optimize the photos (and reduce the file sizes) by processing locally and overwriting the images in the cache.

same problem here, i used the above code snippet, which worked well but shouldn't K2 be able to just replace the image and clear the cache automatically w/o us have to clear the cache of all images?
thanks
