Animating background

Im not sure how to animate background that moves to the right with 8 different slices 960 width. e.g

This is screen , images start and go on the screen .. |.....screen......| <-------- |image1| <--- |image2| <--- |image3| etc..

.. one by other . So they push their selfs and format and illusion by moving backgrounds images to right .

Should i do it with NSArray ? or what technique is used for this ?

I currently did a push one but it don't work . It works for my obstacles to move so they push their selfs to the right but as i did that on images , I'm my order instead of random as the obstacles.

E.G images : http://scr.hu/2icp/iltvf

What is happening :


And other image should come behind it till 8 then restart .

For anyone telling me to watch something again or to get better used to frameworks etc.. well this is my way of learning to make what i want and apply it over and over again in my projects etc..
