Alright, I have almost all of the PHP code done, now it's just for the javascript and niceties. The tag system isn't hardly implemented yet.

The idea is that at the bottom there'll be a little check box next to all of the tags (listed at the start of
the text file), and "random", "next", and "previous" buttons. They will find the next/the previous/a random image that has all of the "checked" tags. Boxes will stay checked from page to page, each time you go to the next page, unless there are no images that match all of those tags, in which case a "sorry" message will appear, and you can adjust the checkboxes.
I haven't done much javascript before, and I might only need to use it for the "check none" functionality, but... well Iunno. I haven't really worked with forms or javascript before, and certainly not php, javascript, and forms all at the same time. xD I'll try to get it finished tomorrow though.
[edit]
note to self: replace all comment links with ones to index.php, instead of the direct image link. add a "perma link" and "embed" thing. if IE is detected, there should be a warning on all [anim] tagged images, because IE sucks with animated gifs. also, get rid of the blue image border.

Tell me if there's a broken link to images in a thread I post, and I'll fix 'em.
