I believe the laws are clear that purchasing an image that is copyright protected gives you the right to own that image yourself, but NOT to distribute it as Gen says. It can be referenced WITH Gen's permission, but NOT for profit, UNLESS, again, Gen gives permission. The unfortunate problem in this situation is if it is shown to one person on the internet, it's like it's shown to everyone which dilutes the value of her work. It isn't like you purchased the calendar and showed it to a few friends privately, which I imagine Gen might like, but instead it is shared with a broad network of disassociated people certainly lacking privacy.
It is certainly rare for a model or an agency to come onto this site and advocate for their rights as creators of their art, and it should be pretty clear how earnest Gen is about her feelings on this matter. Her pleas seem genuine. Just out of respect and as fans we ought to rethink this.
Oh, by the way, if you're still reading, Gen, you just went way up in my eyes.
