All my thumbs work on 5 of my albums but not the 6th. Also, the pictures do not display properly on this sixth album. The site is http://www.parkhabitat.com/zenphoto/ and any help is greatly appreciated. Thanks!

It could be a PHP memory limitation... are the photos in that 6th album larger dimensions than the others? If so, check out this post for a possible fix:

If not, first check your cache directory for the files, if they're there, it might be a bug with some kind of naming? Try renaming that folder?

I renamed the folder several times. I added
`php_value memory_limit 5000M

php_value post_max_size 5000M`
to my .htaccess but that did not help. Any more ideas?

I may just try resizing the images on my computer than re-upping them.

Resizing them worked like a charm. Thank you! (and I finally found a use for Automator)

Yeah, usually you don't want gigantic images up there anyway Takes too much space, right?

If you do want to though, ask your host to modify the php_value memory_limit in the main php.ini to give you a little more headroom.

I'll also be working on a way to split up image processing into separate chunks to avoid this limitation in a way future version.
