I couldddddd use some help with this.

I work on SAI, but used to have PS as my main drawing program.
Photoshop doesn't run well enough as to use it in my computer, used to make some gif/short animations there but tbh I can't really work on it anymore, it just runs horribly.

Any software ideas for short animations, like for gif icons and such? Mostly to fuse and configure the frames, etc, I could still draw them in SAI anyways.
I'd really like to make some animated icons for christmas or smth :_<
