+1 for GraphicsMagick; for many things you can just prefix the command
with gm i.e. "gm identify logo.png" to use it.

The ImageMagick port is barely maintained at the moment. If anyone wants
to take a shot at updating, please send a diff here with a list of which
dependencies have been tested, then I'll do a bulk build to see if there
