Giddyup said "I just did this at Walmart, pics are done in 30 sec. just plug your phone in the machine and chose the pictures you want to print and they print right there. The picture quality isn’t wonderful, but ours was for a school project too so it was good enough for that. "
that's what I've done as well for my genealogical photos & they are really cheap. As mentioned, the quality isn't spectacular but for a project should be OK. It's often quite busy at the WalMart photo processing - coming early morning is a good time.
