I am looking for a simple, command-line resizing/cropping tool, too. (I'd still love to have imagemagick on the 770, but any working alternative will do.)

I never knew about the online services, but of course they are not really helpful: After all, the reason why I want to make pics smaller is that I want to avoid sending the large files over a GPRS-connection. :-)

Teemu, how would I get the Python Imaging library onto my 770? Is there a package I can install?
