    Return 403 on images you can see but can't modify

    Visible images return 404 (Not Found) when you try to modify them and
    are not allowed. This patch changes this return to 403 Forbidden which
    more accurately reflects the situation, in light of the fact that we are
    not trying to hide the existence of the image in this case.

    Fixes bug 1078520
