    Hi, would it still be possible to enlarge a wallet size wedding photo despite having incorporated graphics onto it?

    What do you mean by "enlarge a ... photo" can we ask? You can make a copy negative and enlarge the copy negative.

    I assume the original negative is missing or you wouldn't have asked.

    The best way to do that would probably involve a system which uses zeros and ones...

    I have successfully duped photos from prints in an analog way, but it takes work and planning. If it was colour, lacking dupe film production any more, yes, scan is a viable approach.

    If b&w, and you can successfully shoot it as a macro subject, with lighting to light it uniformly, and avoid reflections (standard technique is crossed polarizers between the elns and the light sources). , and meter on a grey card, or with incident techniques then account for bellows factor to work out exposure with the lens a few stops down from wide open. Expose and then develop longer than normal to expand the tonal range of the negative. Otherwise you will have a very low contrast neg, and printing on higher contrast paper to try to compensate will not give a very nice end result.
