I worked in a Walgreens photo lab circa 2004. At the time the mini lab kept a scanned copy of all images for at least 90 days. I think it was set to use rolling storage, so the time frame wasn’t definite.

On another note, the photo techs will be looking at your photos - at least, the good ones will, so they can adjust for color balance and exposure. The really bad ones will too, so they can keep a copy of any “interesting” photos.

When I worked there, I called the police about once a month, for exactly the reason you might expect.
