Rights-grabbing terms for photo submissions from outdoor sport retailer REI:
1. I irrevocably grant to Recreational Equipment, Inc. . . . in perpetuity, for no additional consideration, to use the photographs or pictures . . . an unlimited number of times in any manner REI deems . . . without restriction as to changes or alterations, or reproductions . . . . I also consent to the use of printed matter in conjunction therewith.
and it gets worse from there.
