Okay, I'm done updating it. I can't directly control the quality of the images, so there may still be a few somewhat ecchi images that are labeled as safe, so be careful.
Changes I may yet make before creating a whole new version are support for tag blacklisting and support for searching more websites.
And here it is.
http://wall.org/~lewis/aii.cgiI put a lot of time into making this interface, and I'm really proud of it, so please tell me what you think of it!
Among other things, I think I need a better name for the next version, so if you could help me come up with one, I'd appreciate it.
Some info about how this works: The websites it searches are tag-based. So, if you want, say, pictures with cat-ears, search for "cat_ears". Note the underscore, which replaces the space in multi-word tags. You can search for multiple tags at once by separating them with a real space. You can keep it from including post with certain tags by prefixing the tag with a minus. So, if you want wings but not bat wings, search for "wings -bat_wings".
