I was given a Kodak SV710 Digital Photo Frame for Christmas - 7" - ideal present for displaying photos of Kintyre.
However, I was very disappointed as the photos had to be reduced (so I thought) to 480 x 230 (that's what it said on the box) reducing images that small from over 2,000 pixels made them look awful. The manual that came with the frame does not give any information on what pixels sizing to reduce to......
I have been playing around this evening and discovered that the ideal pixel size is 2555 x 1345, you may have to crop your image to that size, selecting the best part of the photo for display, but it is worth it .......superb quality images now - much happier bunny !!.
Hope this helps for anyone else trying to make their "huge" camera images fit their digital photo frame
