I have been contemplating increasing my microsctock portfolio with more sports images.  I was considering using some model-released images from games at local events, with the logos and other identifiable markings removed, and even some posed images.  Then I started wondering about what happens if those kids move on to NCAA sanctioned programs.  Could the existence of released images cause problems?  Would it matter if the kid were mine versus someone else's?  I am trying to figure how the money-making part would fit into all this and the NCAA sport.  It seems any photo of a kid making money could be an issue if the kid is in any way related to the photographer.  For example, consider these images:





I realize these are posed, but the potential issues seem the same.  Hypothetically, suppose one of these people later wanted to play college basketball.  What are the issues that could arise from these images being on a stock agency site?
