How do i add the concept art into the background? Every time i does it it says its in the background images tab, but doesnt show up.

Hey Seamus, you'll have to be in orthographic view for it to be visible. An easy way to switch between ortho and perspective is either 5 on the number pad or turn on Auto Perspective in the user preferences so that 1,3,7, and 9 on the numberpad will auto switch to it as well.
