i'm probably bringing this up because my expertise in the area is poor...BUT,
when one sees a photograph (or painting, drawing, fractal, etc.) that he or she selects to print one would put it in a frame. maybe it's because this is a wallpaper site that so many of the members make a frame ON the photograph. i find this interesting and a bit perplexing and wanted to hear what others might have to say. please note, i think the frames that are being placed on the photographs are beautifully done. it's just that a frame done directly on the photograph and an after printing external frame seem would seem a bit confusing.
