I found out that you need to change $HTTP_GET_VARS to $HTTP_POST_VARS and it works properly again, with or without register_globals on. I've posted it as a bug to the core modules in the bug database.

I am left with one problem which I have been unable to solve, and that is the album description. I tried the fix suggested but that did nothing. I also tried using $album.description instead of $album.album_desc in xoopsgallery_index.html, but that didn't help either.

Not only does the description not appear, I can't even find where I might be able to change it. Looking at the code in view_album.php suggests that there should be link to edit the description on the gallery page, much like the one to edit the album title, but I get no such link.

OK, progress... of sorts: I edited the database table row for the xoopsgallery_index.html template directly, then deleted the cached template and... [drum roll, please] the descriptions now appear!

I saw you posted elsewhere that you're working on an updated version of this module. One thing you may want to look at is problems caused when giving marformed HTML code in a description. I did that in one just now: left out a closing ". The pop-up that appears when I try to edit the description now is all messed up. That's my fault, of course, but it would be nice if there was a check for it.
