"Previously we have looked at some tutorials for anyone, new or
advanced, to try his/her hand at creating artwork in GIMP because
it CAN accomplish phenomenal works, especially in conjunction with
other open-source software. Here's a fun tutorial to cartoonify
photos in GIMP (like you see in ads all over the web), here's
another one on creating image maps, and there's also one on
creating a zoom effect on screenshots. I'm certainly really excited
about GIMP if you can't tell already.
"As a GIMP enthusiast, I learn mostly from following online
tutorials over and over till I don't need the instructions to
repeat the steps anymore. That's how I learned to do the
zoom/magnifier effect, which I badly needed for some of my
screenshots. Here's another such tutorial that's out of necessity
for anyone that blogs and needs to point at and annotate some part
of the screenshot."
