Apache/2.2.3 (CentOS)
php 5.1.6

Joomla! 1.5.1
RSGallery2 1.14.1 Alpha - SVN 709

I've tried tons of releases, and none seems to have a working description field
the alpha version won't even install for me, so I'm strictly nightly builds now

if you include the description when you upload, its fine
but you can't EDIT the description after you upload

apply or save don't work when you try to add description text and save
it just says "done."
but erases whatever you put in the description field

would also be super cool, if we could remove the label that says "Description"
I'm trying to find it in the code and remove just the label...but havn't found it yet in the code

workaround is:
add your description text at the same time as you upload.
