imagemagick is one of those secret programs that people outside (and
many inside) the linux world just don't know about, yet its so
powerful, easy to use (scriptable!!) that I don't know how people can
live without it. Compare the ease of resizing a batch of images and
producing thumbnails using convert versus the same job in any of the
clicky gui programs. Simply amazing. Don't get me wrong, I love the
Gimp, but you can't beat convert for so many things.
