Fullscreen slider / button to go out of fullscreen

[Louis 0]

hello,
I want to be able to display my photos as a normal grid layout but when you click on it go into the fullscreen slider and have a button in my fullscreen slider to go out of the fullscreen slider into the normal grid layout again. like here:

Can someone help me with that?
