If you are on Photoshop CC 2015, you can open up your photo, go to File -> Export As and open the export as menu. At the top right, choose JPG as the file setting and export the file. You will need to upload it to the Shutterfly website from there. If you have an older version of Photoshop, just open the photo, make your edits and File -> Save As and choose JPG. Again, take that file and upload it to shutterfly to order it.
