    this is the rules:
    Image File Format:
    The image must be in the Joint Photographic Experts Group (JPEG)
    format.

    Image File Size:
    The maximum image file size is 240 kilobytes (240 KB).

    Image Resolution:
    600 pixels high by 600 pixels wide.

    Image Color Depth:
    24-bit color [Note: Color photographs are required. Black and white,
    monochrome images (2-bit color depth), 8-bit color, or 8-bit grayscale
    will not be accepted.]

    but in my photoshop i have only 8-bit and 16-bit. (see the attachment)
    so How can i create 24-bit JPEG file for DV-Lottery?
    its very immediately, plz.

    oh that's going to be tough!

    the Joint Photographics Expert Group was a committee, they never made a format that complied with their specifications.

    I hope they'll allow you to use a JFIF, JPEG File Interchange Format image, cause that's the closest implementation to the specification that we have now.

    Jpgs by definition(the native files) are already 24 bit: 8bits for Red, 8 bits for Blue, 8 bits for green!

    I.E. they are 24bit RGB

    In Photoshop, when you see 8, 16, 32 ---> bits = that is really BITS PER CHANNEL

    so a 16bit file in photoshop would have 16 bits for R, 16 for B, 16 for G

    make sense??
