For "Almost": No Black & White. No pics of just body parts; there needs to be a smile (or grin, smirk, laugh, etc): the models should look like they want to be photographed. No porn, no men, and bland backgrounds & fake cushions are avoided. Also, no self pics; only reason I can think of for a girl to take a self pic & distribute on the internet is because they're underage. For "Duke Malibu" puzzles, the model can be expressionless, but the pic must have artistic merit.
