Okay I have a question.

Say I have this background image
/images/forum/upload/2015-01-11/c270a42e65d6915fccaf26a4ea2a4be7.jpg  And I want to have this image scroll over top (with the same distance between each image) of the background image.  Clearly I would need an image that would fit each angle and size but you get the point right?

What would I need to do in order to make this happen?
