I have a bunch of images. Each one is going to have some text associated with it (a headline and some body copy).

I need a forward and back arrow, and it needs to scroll in each direction indefinetely (not while holding mouse down, but if you hit next when on the last image it needs to go back to one, hit back on image 1 it goes to the last image).

I don't even need it to visibly scroll or animate in any way, just on click content changes.

Images and text need to all be loaded from an XML file.

Oh yeah...and they want this by end of the day.

If you can even direct me somewhere I can purchase the code to do this I don't care. I just need to get it done.
