Unfortunately, the client supplied me with these images. I’ll have to make sure to forward a note to them after I build the CMS upload for this gallery.
Actually, the photos and thumbs are all in the same folder being called by PHP from the same source.
I’m suspecting it’s because of the extension. The thumbs are ‘.jpg’ while the larger image is ‘.JPG’. Why that would make any difference on a live server is beyond me.
the thumbs are simply not in the folder they should be in (photos). how are they generated? if the script is generating them, then make sure it has write permissions in the folder.
