    jpg's have a header, and that information is all in there.

    Go here and download the information for jpeg.

    Oooooops. I kinda lied a little. You said size. Most graphics formasts map data onto a device. The physical output device can be any size, so size is purely relative. In other words, there is nothing that says 'I am a picture that is 10cm x 40 cm"

    Oh, you must mean pixel height, pixel width, and bit-depth. That information I believe is found in the JPEG header
    Things I've Said:
    "Life's funny like that...elephants can wear frilly lace panties, and Dubya still looks like a monkey in a big chair"
    "Take four goats and strap one to each foot of a llama. Presto, goat-powered llama!"
    "You want to get me to work more, get me a Coke. No? Then deal with inferior garbage, I'm not coding another line and your clients can go to......thanks, I'd love a Coke right about now!"

    I found this at www.freevbcode.com

    Follow this link and download the file listed, it's a sample program with source code for getting info about image files.

    They've got a lot of good code there besides that
