Ok, well first, Go to your desktop of course and locate Photoshop 

Open Photoshop!

Open a GIF of your choice. 

I would choose a GIF that is short.

You should have every layer of the GIF in your “Layers” table

Make sure that Layer 1 is the ONLY one that is visible and also is the one you currently have selected.

Open another picture (It wont get rid of your GIF you opened)

(Yes I am going to use Hetalia for this) 

Next, select the “Magnetic Lasso Tool” and select the outline of the face you want to use.

Your face should be outlined with black and white moving dots (They wouldn’t show up when I took a snapshot, so I outlined it in aqua)

Hit CTRL + C to copy the face 

Go back to the GIF you are using and press CTRL + V and your face should appear on yout GIF like so:

You face should also be in it’s own layer 

Keep the new layer visible and currently selected and right click (before your right click, I would make sure you switch from Magnetic Lasso to Rectangular Marquee Tool) on your GIF and select “Free Transform”. It will select the face since it is the layer that is currently selected.

Mess around with the face so it covers and fits over the original face of your GIF 

Go back over to the layers   and right click on the layer your face is on and select “Merge Down”

It should now look like this:

Select “Layer 2” and make it visible

Go back to your GIF and hit CTRL + V, it still has what you copied from last time. So, the face should appear on the image again:

Free Transform the face, mess around with it so it covers and fits over the original face of the GIF

Right click on the layer the face is on and select “Merge Down”. 

NOW REPEAT THESE STEPS UNTIL YOU ARE COMPLETELY FINISHED.

Once you are done, DO NOT SAVE, SAVE AS, ETC.. You must select “Save For Web”

Something like this should pop up:

Go over near the top right and make sure the “Animate” box is selected 

Go down towards the bottom right and make sure your Frame Delay is set to “0”

Somewhere you should find something similar to this:   click on the globe with the question mark to preview your new GIF to see if it works properly 

A new window should open and you will see your GIF (Mine is set on IE for default, I don’t really use it. I use Chrome)

Exit out of the window and go back here:  and hit “OK” then you name it whatever you want in whatever folder you want it to be in.
