I'd just do that directly in bash.
for fn in *.png; do mv $fn $fn.bak; convert -crop whatever $fn.bak $fn; done
But that's assuming you know how to use 'convert -crop' to do what you
want, which I don't. Personally, I'd whip up a quick Pike script, or
even do the job at the Pike interactive prompt; but that's because I'm
familiar with Pike's image library. (Happy to elaborate if you're
curious, but unless you have Pike installed already, it'll almost
certainly be easier to use convert.)
