You just combine more than one gif on a canvasTry this tutorialThe person does the stacking horizontally but all you have to do is do it verticallyHere's a YOUTUBE video of a vertical stack with 2 gifsMy tips are to make sure your gifs have the same number of framesAlso put each gif in a folder of it's own and then move them around so you don't have to mess around with lots of layers. If you look at the layer panel and see a small folder sign next to the bin symbol to delete a layer that's what you need. Then drag the layers of gif inside it. Helps keep things organised when you have lots of layers.Any issues PM me.
