How do I get a background to repeat on itself and wrap around from right to left vica versa.

I am trying to replicate this: Grand Theft Auto V

I am using their background atm, http://www.rockstargames.com/V/img/global/home/lsbc/local-artisans/bg.jpg

At the moment I am trying to create a template ready for me to use in an upcoming project and I am still learning the ropes.
