I've made frame by frame animation by saving each animation into one sprite. Like this.

The only difference is that I used a lot higher resolution. The biggest resolution I need for a single frame is 800x600 px. Yes, that's a lot. Result is 13600x3600 px image. And it appears that's too large for AS3, as it doesn't appear on the screen (900x600) at all. I loaded with smaller image, it works fine. It' just that this one is too large.
How do you handle this kind of image, or frame by frame animation in general?
