and most of what I post on this board. You can register and get some amount of free storage space for a gallery. It's basically a forum site with the ability to store images for discussion.

If you resize for web display, you can get quite a few images on the site and organize them by topic. http://photocamel.com/gallery/showgallery.php?ppuser=9417&cat=500 is my gallery on that site.

I won one of their contests before they got sponsors to put up prizes and ended up with a lot of storage as the prize.
