Not sure, that would require a database redesign and I don't want to force people with a current install to do that. Also, it seems something like that would work better for a whole new script, properly designed around the idea.

> config.pl parameter for a generic image that takes the place of a deleted image (ie, Hello Kitty)

Ah, good, been meaning to do, forgot about.

> Fine-grained banning options that let you choose whether or not the user is blocked from reading a board, posting to a board, or both. Another parameter defines the duration of his ban ('0' for permaban), and another defines a reason/message displayed when the user tries to access a board.

None of those seem useful to me, because I'm of the opinion that bans are to prevent abuse, not to punish users.

> Replace HTML error pages with dialog box equivalents using JavaScript.

Would require a bunch of hidden-iframing and such. I'd like to do a complete re-design full of javascript trickery, and this idea would fit better in such a context... That is to say, I'm lazy and the current version is robust, and I'm loathe to go around changing it, since it would introduce new problems.

> Kill user deletion. I can't see any case for when it'd have constructive uses.

On image boards, it has a very definite use - people do fuck up and post in the wrong thread, or create new threads. It's better if they can clean up after themselves. In Kareha, you can already disable deletion.

> Conversion to mod_perl?

As far as I know, it should work in mod_perl already, modulo some prototype bugs. I'll try to get those fixed.

> The standalone thumbnailer project is a great idea too. As a suggestion, how about adding functionality to also read and thumbnail document files like TXT, PDF, and DOC?

That would require a LOT of code, especially when you don't want external dependencies, so it's a bit iffy.
