Users with this badge are image moderators. Image moderators have special powers on ROBLOX that allow them to approve or disapprove images that other users upload. Rejected images are immediately banished from the site.
The Image Moderator badge was given to people who were invited to be Image Moderators. The badge was removed in 2014.
The image moderator badge shows up as a decal when an image, a shirt, a pants, and a T-shirt is being reviewed. It displays an image of two pictures of sunshine and hills. One of the pictures has Santa walking with his bag.
