Ok, easy, just learned some time ago: you take your fist frame, than in Image Ready you create as many layers as many frames you need. And then you also create all the frames in the bottom window where all the frames will be.
The, you just open the second frame (if already created), select all, copy, and paste it onto the first frame, but on the second layer. And so on... when every layer has its frame, you just select in the bottom window, the second frame, and in the layers window you put the "eye" on the second layer.. and so on... and shit, my explanation is terrible.. but it's 2.30 am here!
