I gave my sister an iBook G3 Clamshell with OS X 10.2.8 for Christmas. My parents gave her a digitizer. The digitizer works fine on the Mac but I cannot find a good Image editing program for her to use it with. I tried the GIMP but I cannot figureout how to install it or what vertion to use with OS X 10.2.8. And I can't find anything else that is as good or free. Help?
