If your image(s) of bondage do not qualify as 'acceptable', for one reason or another, you might try Renderotica.com. But I believe if your images are 'tasteful' then you should have no problem. If they venture into pornography, then perhaps it would be best if you tried another place, such as Renderotica.com. Hey, I'm all for freedom of speach and expression, so long as it does not become hurtfull.
