I think Hal is in there! [

If you take it down to Staples, or a similar place, they will enlarge your on screen photo to whatever size you want. I've enlarged pictures by doing it my self, but the $20 or so I spend having them do it saves me days of effort. We may have an unusually sweet group at Staples here, but they always do exactly as I ask. Oh, the last thing that was enlarged for me was 1.5 inches short of the requested 4 feet! I told them it was fine. No one is ever going to know or care about that.
