i hacked Futallaby to allow images in reply posts. on !WAha's suggestion, i made sure the image replies were deleted when their parent post was deleted, too. if anyone's interested, i'll put the script somewhere to download. it doesn't take any additional config options and it uses the same database structure.

it's in use on a fairly slow board and seems to work well, after some showstopping post deletion bugs got taken care of and some posts were readded via SQL. :)
