Can someone please explain me how to save each slide of a
gif animation as a
png file in Adobe ImageReady?
It's been quite a while since I've launched Imageready and no longer have it available to test.
By "slide" I assume you mean animation frame. In the animation panel There may be an option to save frames. If not, there is an option to flatten frames to layers. This would create a new layer for each frame of the animation. You could then simply export or save each layer as an individual image.
