Zimmerman faces trial in the shooting death of Trayvon Martin.
Cfnews13.com reports one of the new photos shows Zimmerman in a cap and gown during a graduation ceremony at Seminole State College.
Martin was shot and killed on February 26, 2012, while returning from a nearby convenience store to his father's fiancée's house in a gated community in Sanford, Florida.
Zimmerman, a neighborhood watch captain, acknowledged that he shot the unarmed 17-year-old, but said Martin physically attacked him and he fired in self-defense. Initially, no charges were pursued, and the case soon became the center of a national controversy.
Zimmerman was charged with second-degree murder on April 11, 2012.
The Sentinel reports that five of the photos show Trayvon about an hour before the shooting as the 17-year-old bought Skittles and a soft drink at a 7-Eleven.
