I have about 1,500 photos on an SDHC card and expected that the frame would show all of them. Indeed the manual that comes with it says that it shows up to 9,999 photos. However, it only shows 465 of the pictures and when doing a copy onto the internal drive (which should be big enough using their 'Smart Copy') again only 465 photos get copied.
The pictures that show have excellent quality ... just that I can't see all of them.
Oh, and the frame support for having it on a desk is pretty poor - doesn't give enough vertical support and easily collapses.
