Edit metadata in an image

Im am trying to store metadata into an image. The metadata "fields" (or whatevere they might be called) should be specified by me and of course the values of these fields as well. Is there anyway this can be done in Pascal? If not could someone point me in the right direction?

    What Sort of image file?
    If it is possible, then it is possible in pascal. If you try to add a metadata field onto an image type that doesn't support it, you may screw up other programs trying to read it.

    Well, lets say it

    A bit more complicated than i thought. But if I can
