Since there is no picture attached, there is no certain way we can answer this question correctly. However, I found on the Internet some answers (provided that the photo in your question is that of a samurai in mid-jump):
1. The forces which are on the man are unbalanced, given that the man is moving. If he were stationary, the forces would be balanced.
2. Gravity and resistance are the forces acting on the man.
3. What happened to the man after the photo was taken was that he reached his highest point and then fell down again.
