Hello! I do not have photoshop, so I don't know if photoshop supports animation or not. I use Paint.NET and I know it doesn't. So here is a simple way of making animations... using this program...

AND this picture

.
Firstly you make the pictures you want in the animation and save them as ".gif"s. You then open the program, as well as your "pictures folder" or wherever you saved it...

You then drag the pictures from your folder into the program... I put in two of the first picture because I wanted it to last longer then the other...

You can then change the loop time and make your animation!

This is how mine came out...
