Edit images at console

[Black666]

Hi!
Somewhere I've read a nice article how you can customize images right from the console.
The functions I'm looking for is resizing (making a 1600x1200 image to a 1024x768 image) and making thumbs (for a 1024x768 image a 32x32 thumb for example).

I only remember that it's really easy...only a short line at the console...

Please help.

Here's several methods for it from the Linux Cookbook:
