For years i used "paint shop pro version 6" (1999). And before that I think I used earlier versions of the same thing. The thing I liked about it was that rather than thinking in inches, it did everything in pixels.
Eventually, I tinkered a little with the animation thing. Like the little bunkhouse with the smoke at the bottom. And the fly on the moose.
I'm able to cobble things together with paint. But I liked paint shop pro 6 better. I once bought paint shop pro 10 and spent several months tinkering with it - but that got really complicated. I really liked version 6 better.
I tried GIMP for a while. I didn't quite get the hang of it.
Anybody have any suggestions for something that might be good for simple drawings that are pixel based - and has some animation stuff too?
