Here is a 6 sentence paragraph describing the actions of people in a picture using simple present tense verbs:
The picture shows a group of friends spending time together at the beach on a sunny day. Two people are playing volleyball in the sand while another sits and watches them. A woman is reading a book under an umbrella and does not seem interested in joining the game. Two others are in the water swimming and splashing each other. Nobody is sitting around a campfire or cooking food, as it seems like an afternoon of relaxing at the beach rather than an overnight trip. Overall, the friends in the picture are enjoying some leisure time at the beach on a nice day.
