I would happily download this plugin, and even pay for it if you made it work a bit like how standard galleries work (facebook, myspace, etc) that allow visitors to comment on individual pictures.
So far every single gallery plungin for wordpress just lets someone comment on the entire gallery or album, which doesn't really make much since.
i've been using an entirely separate script for my gallery (gallery3), but it would be nice ot have something built into wordpress via plugin.
please consider this. thanks.
