Amateur rocket launch reaches 121,000 feet
Can't they confirm that the altitude met the contest minimum based on how much earth curvature there is in the photos?

They would have to compensate for artificial curvature introduced by the cameras they are using. If you look at the images you can clearly see that effect.

They should be able to do that. No?

Yes camera calibration is a well known problem. You have some nice straight lines from the launch pad structure you should be able to do it with.
