Retrieving thumbnails from a photo library

I want to save thumbnails from the iphone photo library, and I want to use them in my application, but without selecting them, I want it to work automatically. so I started the application and the thumbnails appear in the middle of the screen in a scrollable table view. (5 fingers on each page). For example: http://cl.ly/0z2m261J2I0B461n2L25

What is the best way to do this? Oh, and, of course, if the user touches the speaker, a large image will appear in a different form.
