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 as those may not have been intended for anyone else to see. For "Duke Malibu" puzzles, the model can be expressionless, but the pic must have artistic merit.
