I finally got some good side shots of my fainting goats so now I just need to mail off the registration applications, but I'm having trouble with the photo sizes. The application says: "Two pictures of one side of the goat must accompany the application. Photo should be approximately 2 ½“ x 2 ½“ in order to fit on the registration certificate." Would a regular wallet size photo be okay? I think that is the smallest size you can get printed? Or should I buy my own paper, print them myself & measure it? Shutterfly wants $28 for 16 wallet prints (plus shipping). I'd hate to buy them & then they say they're too big.
