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. :) A
