If your still building the picture frame (the 5300 is perfect for this) Use the Compact Flash adaptor instead of a Hard Drive (silent & less power), Pop an old wirless card in the PCMCIA slot, then share whatever folder your image display software is pulling from. Then you just log onto the shared folder and drop in whatever pictures you feel like looking at today. You can also intall remote desktop to make interfacing with and maintaining the picture frame easier. Artistcally, the nicer ones look as much like a real frame as possible, ie use a real frame and hide all the Tech. (but then the opposite, say an acrylic look w/ exposed electronics would also be cool) Have fun!
