How do I create sliding images on a surface GUI?

I need to know how to make images slide on a surface GUI over and over again in Roblox. I have looked everywhere for a tutorial but cannot find a video or tutorial

You can use Tweens to do that https://developer.roblox.com/en-us/articles/GUI-Animations

Its really simple, play with tweens a bit and youll probably be able to do it Also use a local script for that.
