What's the easiest way to print photos directly from my phone without having to mess with a computer, especially when I'm on break at the clinic?

Okay, so I'm usually dead tired after a 12-hour shift, and the last thing I want to do is mess with my computer to print photos. I just want something that works, you know? "Photo Prints Now: CVS Photo" is surprisingly simple. It connects directly to CVS, which is perfect because there's one right by my apartment and another near the clinic. I can upload photos straight from my phone – usually pictures of my niece – choose sizes, and place the order. It’s like having a pocket photo lab, but without all the chemicals. I’ve been using it for about six months now, and it's actually reliable; hasn't crashed on me once, which is a big deal. It's a no-fuss approach that I really appreciate when I'm running on caffeine and fumes.
