How to take the pictures of your iPhone so you can hang them on the wall?

How do you do this? I don't want to print them out, I want it to look and feel like a real picture. Like when you go to Costco and you could have your pictures taken out of your camera? Can you do the same with the iPhone?

You can always copy them to your computer and print it out

Costco has an app, which you can use to upload photos for printing.
