Is There A Free Photoshop Alternative for Mac OS X? I've been doing quite a bit of searching, but I'm only turning up commercially licensed packages.  I don't need something as fully-featured as Photoshop, but something in that genre is sufficient.  These features are of most importance to me:


Basic photo editing
Some filters
Layering
Text tool


I want to be able to make simple posters/flyers by combining multiple images and text.
GIMP is widely recognised as a quality free alternative to Photoshop in many regards.



...but it's not considered to be particularly successful in it's approach to embracing Mac OS X application design ;)

If you want something that isn't necessarily free but is at least inexpensive, then there are a number of other programs including Acorn and Pixelmator available in the Mac App Store.  You could always try the cut down Photoshop Elements.

For a good roundup, see this wonderful blog post from the Ask Different Community Blog for more info:
