As is the case with so many people who go viral based on a picture, internet fame didn't do much for Stokke financially. Nor was she earning any money out of pole vaulting when she came to the world's attention; amateurs don't get paid anything at all!
Fortunately for Stokke, she's extraordinarily beautiful. Her good looks attracted the attention of several modeling agencies, and doing part-time modeling work helped her to pay her bills during her years of training.
