I give my customers images in two sizes, one is Q10 sRgb jpeg at native camera resolution, the other is around 900 pixels which is ideal for facebook. That'd work for TVs as well, though resolution may be a touch low.
JayADee: I'm just finishing a book layout for a guy that involves a lot of scanned photos and some photo restoration. I'm going to put the photos and a PDF onto a dvd for him. What's the best/most flexible file format for the photos given he's not technical at all but he does have a recently purchased laptop? I don't think it likely he'll want to print them out. They are psd files. TIFF maybe? JPEG?
Thanks for any advice.
