1. Click File -> Import -> Video Frames To Layers
But when you open the "Import" window it will only allow to open .MOV; .AVI; .MPG & .MPEG files.
2. So if we want to make adobe photoshop to allow us to open any files (including GIFs) we need to write *.* and press Enter into the import window.
3. Open the desired animation (in this case animated gif file)
Hope I helped someone
