I use convert. I think it came with ImageMagick, I'm not sure. Something like this (zsh shell), for creating thumbnails:
$ for i in *; convert -crop 80x80% -contrast -geometry x118 -sharpen 30 $i $i
Or to resize an image:
$ convert -geometry 640x480 foo.jpeg foo.jpeg
You should sharpen a little though, if you're scaling down. Also, I rember seeing some filters implemented using stdio, so you could pipe things too, but I cant rember the name.
