I don't have a picture for you.But if the belt broke ?
You need to spin all the pulley's to check if they are free.
Note if it is a 4.3 or a 5.7 also S-10 or K-5
I am thinking 4.3 little blazer
Crank up left of the water pump right to the p/s over a/c under tensioner over alt.
This is best i can do. Good luck.
