Warning! To all my author and designer friends, DO NOT purchase stock photos from Vitaly Sokol, AKA Willyam Bradberry on Shutterstock! He is totally trashing the reputation of a VERY reputable artist, being rude and unprofessional, and threatening to sue over a COMPLETELY LEGAL use of his image.
Just a warning. Avoid his stuff like the plague unless you want to get into a lot of potential trouble for no reason whatsoever.
