SlideNswap is a pretty cool plugin,
It makes your image slide inside a frame and then swaps it to the next one.

To really understand what I'm talking about see the Example Page

Requirements:

• jQuery (used 1.5.1, but probably works with older versions)
• jQuery Background Position plugin

That's it!
