I recently ran across this amazing tutorial during my Pinterest browsings that totally caught my eye!!! It said, "How to Print Instagram (or Square Photos) at Any Retail Photo Center" So, I traveled over to Ashley's page at Lil Blue Boo and read her amazing tutorial!!!
Instead of trying to create my own tutorial, I am just going to send you to her page!!! She has given such simple and clear instructions!!!
I will mention one thing, though. When I uploaded my Instagram photos, none of the pixel sizes matched her charts. They were either too big, or not listed. So, being the complete math dummy that I am, I spent part of the afternoon trying to figure out in my mind how to adjust the math to get the correct pixels...
Then I had an "Ah, ha!" moment!!!! DUH!!!
I first had to adjust the image size- so instead of using pixels, I used INCHES!!!! (duh, right?!)
I changed the image size to 4x4 inches (since I would be printing a 4x6 picture), and the canvas size to 4x6.
Eureka!!! Problem solved!!!!
I then proceeded to upload 77 photos!!! ...I had a little problem uploading to the site, so it repeated about 17 photos, so I was really at more like 60 :) ...that's better, right?!
I hope you enjoy printing!!! The only down side, is that I don't know how to do this if you don't have Photoshop or Photoshop Elements :/ But, I hope this helps!!!!
