I have some JPGs that I would like to have printed and then frame them for myself. They are in the 12x18 size range; photos and posters. I don't have a high quality printer so I took a quick look online and saw a zillion places for printing online. Everything from Shutterfly, Snapfish, Walmart, Walgreen's, FedEx Office, etc, etc, etc. Any recommendations for a place that does high quality printing. My walls are waiting.
