portable slide show circuit

i am wondering if there is a circuit that will enable me to create some sort of portable slide show. Like a box that you plug into the av inputs on a tv and it cycles through the images stored on it. I have seen heaps of mp3 player circuits. or a circuit that would play mpeg movies on a tv would be even better.

Digital Photo Frames

Hi

I have seen this sometimes back
**broken link removed**
This is a digital photo frame which cycles thru images stored in the memory, Sony first came out withis idea, they even had a product but I dont know if they still produce em, if you specifically need it to display in TV, you could get one of these and hack em off.

Another alternative is to get a PC mobo with tv output vga and box it wup with yer favouraite os + slide shower program
