Scrolling and Looping 2D Background Image

Alright, I’m a bit of a beginner here with unity, and basically I’m working on a sidescrolling game, and what I’m trying to figure out is how to get a 2D background image to scroll around as the character moves, and loop the end of the image to the beginning of the image when it needs to. I’m just looking for the basics of how to make this work, and then I can modify my scripts to get this to work if I need to.

What I’ve done to get a 2D background image so far is just creating a 2nd camera to display the image in the background by setting it to have a culling mask for only the background image. I can change my method of displaying the background image to get the image scrolling if need be.
