Covenant, you could even do it in Windows Paint. All you need to do is open that jpg in there, go to image-> stretch/skew, and set both of those at 10% (I'm guessing that should be about right). If everything still shows up too small then, well, you may wanna think about cutting out the parts of that picture that you really don't care as much about. You can do that pretty easily in Windows Paint as well.
