i wouldn't recommend imageshack as they remove adult content, but you can use http://www.imagevenue.com/ just mark it not safe for work in the drop down box.

As for buckrix's question, i have fantasized about a woman crushing my balls but it's not something that i would like to become a reality. i love ball busting and if a woman crushes my balls then that would also end ball busting and that wouldn't be fun
