Hello everyone,
I've around 18000 photos divided in 250 albums on zenphoto gallery.
Everything works fine, but i'm wondering about some image cache info.
I've used the "Pre Cache" tools for all the album to generate the cache for image, but on some image, each time I relaunch the "Pre Cache" tool, Zenphoto regenerate thumbnails.
For exemple, i've an album with 77 images and each time I launch the "Pre Cache" tools for this album, 4 images are always recalculated, always the 4 same.
I've check on the \cache folder and the 4 images didn't have the ***_695.jpg preview

Here, the "052902 (21)" photo have "_100_cw85_ch85_thumb.jpg" and "_695.jpg" cache files, but the "052902 (22)" and "052902 (23)" photo have only the "***_100_cw85_ch85_thumb.jpg" one

What's strange is that it's only some photos (and always the same) that have this issue, the rest of albums are just fine.

Do you know if there's a way to know why ZP didn't create the "****_695.jpg" cache file for theses photos ?

The ****_695.jpg" one are for the "sized image" one on image.php. If they are not created that could have sevaral reasons like actually belonging to multimedia items. These do not get an sized image for obvious reasons.

Besides, it is not really necessarry to use the precache tool at all (see the troubleshooting guide).

Thanks for your quick answer !
