Could GIFs hide coded messages in them? Yes they can. Prosthetic Knowledge put together this "Lenticular Encryption" project to show you can hide something in those fun filled formats.

You won't be able to see it with just your eyes alone. It will take a little analog and digital media to make it happen. Angling a lenticular sheet on top of the screen will expose a whole new layer of data and add another "visual narrative" beyond the animation you see.
