You could use ImageMagick (particularly, the 'convert' program) to do this
but decent results are not fast (not that it'll take several seconds or
anything, but it does take a certain amount of time, and everything adds

If you want to do this on the fly, I'd suggest having it save the 
thumbnails when they're generated so that the next time someone comes, it 
doesn't have to go through the process again.
