Resize image to print

I believe the reason this is happening at Walgreen's is that their machines look for empty space and auto crop....or it's being done through some other auto processing that can't be turned off.  The solution I used was to create empty white space around the edges and fool the machine into thinking it was larger than it really was.  (essentially printing a smaller image on larger paper)   When printed, the resulting photo would have some of the white (blank) space and I would trim/cut it down.

Can you post a screen shot of the image size window, and a scan of the actual printed photo? This might help us figure out what happened.

I've used Walgreens a lot, and never had issues with the cropping. It sounds like your image is sized right for them. Have you tried a different Walgreens or Riteaid?
