Hi! I need to print (via Shutterfly, Mpix, or other) odd sizes of small photos (2.5x2.5 for example). How/where can I crop pics into these sizes and have them printed? I tried cropping through iPhoto, but when I upload them to say, Shutterfly, they still crop it to a 4x6. I thought it would show my image in 2x2 and the rest of the 4x6 would be white, but this is not the case. I don't have photoshop or any other program, so I'm hoping there's an online place for this. Any help would be mucho appreciated!
