I’m going to show you how to make this:

1. Okay so first make your gif like you normally would, if you don’t know how to do that look on basically any photoshop blog and I guarantee they’ll have a tutorial on it.
2. Go to your last frame and hit this button
3. Now you’ve duplicated your last frame, now while selecting the extra frame you just made turn off the layer that’s selected with it.
4. Now scroll down to the first layer and turn it on.
5. now click on your second to last layer and hit this button
6. set your settings like mine

now it should look something like thiss

Add a psd and crop it or whatever else you want to do and BAM you’re done.
