The picture shows Kobe Bryant showtime dunking the ball versus the New Jersey Nets. The picture was taken in 1997-98. How do we know? Keith Van Horn wearing 44 and Xavier McDaniel waering 34 for the Nets is the only year the two of them played together with the Nets.
Fun fact: Kobe is wearing adidas, whom he signed with in 1996 out of high school. He didn't start wearing Nike until 2003.
