    Post file-header of jpg-grafic?

    i know it's probably a little bit off topic, but i didn't know which board fits best for this thread.

    my problem: i want to know at which position in the jpg-grafic the bytes for the size of the image (width and height) are stored...

    e.g. in a gif-grafic, bytes 7 and 8 store the width, bytes 9 and 10 store the height-information of a gif-images...

    but where are these information stored in a jpg-image?

    and, if possible and someone knows, where are these informations in png-grafic?

    thansk a lot...
