    Another question. I haven tried printing with white borders. Will the white border cover the exisiting photo or is the photo made to fit into the white border.

    If you print with border, the picture will fit within the border.

    Strictly speaking, 4R is 4 inches by 6 inches; it is purely a physical dimension independent of pixels and resolution.

    If you choose 300 dpi then it's 1200 pixels by 1800 pixels, but it's really arbitrary. If you choose 1 dpi, then 4R is 4 pixels by 6 pixels.

    Of course, you can't send a (4x6=) 24 pixel picture to print at 4R, but you don't need 300dpi either. At around 120-150 dpi, the print still looks pretty ok.

    analogy:

    the 3R, 4R, 5R, etc ~ volume
    the how many megapixels ~ mass
    the dpi ~ density.

    mass / volume = density ;-)
