DSL Ideas and Suggestions :: Image Management Software

I've got more than 15,000 photos, taken with a digi cam. I'm using DSL more and more (frugal style), but it doesn't have anything to manage these photos so I can't change over completely yet. I use gimp for proper photo editing so no problem there.

Till now, I've been using gThumb, part of gnome (with Fedora anyway). It is OK (feature wise), allowing me to do bulk moving/coping, rename series, exif info, resizing, basic categorising, comments, searching.

imgSeek   http://imgseek.python-hosting.com/   is something that looks like it would be great, but I couldn't get it going with Fedora Core, let alone DSL  

I'd really love something that could do bulk moving/coping, rename series, exif info, resizing, basic categorising, comments, and searching. Nothing really fancy needed. Any suggestions/ideas/solutions?

cbagger01, thanks for the response. Looking at Imagemagick it seems to be basically an image editer, rather like gimp, but a lot smaller and not as powerful.

I'm more after collection management - ie. cataloging and organising type stuff. Perhaps the thread title is slightly inaccurate, and I did mention a few editing functions earlier(which gimp or imagemagick could handle, but it would be nice if they were integrated with collection management). There are several image collection management programs in the Windows world, such as acdsee.
