Walgreens is offering a Free 8×10 Photo Collage when you use code GETONEFREE at checkout through 8/21/12. Choose in-store pick-up, if available, to save on shipping charges. Looks like shipping charges may be $.99 if you want to send one directly to someone.
Through 9/30/12, Walmart is offering a Free 5×7 photo at the Walmart Supercenters with a 1-Hour Photo Centers. You can read all the details on the free photo promotion on the printable coupon on their site. (Coupon is not required, though.) Looks like you can get one free per child.
Thanks to Freebies4Mom for these deals!
Grandparents Day is coming up on 9/9/12. You might be able to use these deals to give a framed photo to the grandparents for not much out-of-pocket.
