dphoadly -- no, the public right of way concept is in no way applicable to this situation.  There is no way that it could be applicable.  Renderosity could choose, if the company wished, to close the site completely.  Nobody would be able to force them to keep it open so that the public could access nudity.  The analogy is too weak to even argue.

And, for all of you who seem to gloss his over, please keep in mind that there are some of us who think that Renderosity has the right (as a business) to set up whatever policies it wishes, and yet we are not opposed to nudity.  I, for one have no problem with nudity in the galleries.  I'm sure there are lots of galleries with naked men and women, individually or together, and some of them are good renders and some aren't.  There are lots of real world art galleries with nude images .... not a big deal.  However, I don't know of a single real world gallery that takes its most graphic examples of nudity and posts them on walls all over town for the public to see while strolling down the street.  If there is one out there, then, congrats you live in an extremely liberal city.

PerfectN .... if that's your preffered way of dealing with business policies, then knock yourself out.  Have a field day.  Complain all you want.  I don't really see what you will achieve by it, but some people just need to vent, and I would hazard a guess that you are one of those.  That's great.  However, the policy is what it is, the moderators are supposed to remind people of the policy, and you were reminded.  So, what happens now is really up to you.  You either choose to comply with the policy or you don't.

I didn't need to go looking for nudity in your image.  That's pretty much the central theme of the image.  Actually, it seems to be the central theme of most of your gallery.  They are really exceptional renders, by the way, you are a very good artist, and I do consider your nudes to be art, rather than what is commonly known as Poser porn.  So, please don't anyone get the impression that I am dissing PerfectN's skill at creating an image.  And, if I ever decide that I need to see a lot of well rendered naked women, I'll know where to go.  

But, the bottom line is, no matter how stupid you find the thumbnail policy, if you are going to post images of nudes in your gallery - as that word is defined by the policy and not as defined by kawecki - then you need to be aware of, conversant with, and willing to comply with that policy.  Otherwise, what will happen is that you will end up getting banned by the site and a lot of people you really like your images will be the worse for it unless they can find your artwork somewhere else.

If they decide for whatever reason, that the side of someone's butt is "nudity" ... then start using their definition or post elsewhere.  Yeah, I know that sounds harsh and crappy ... but that's the reality.  I didn't come up with it, so please don't start bashing me for it, I'm just pointing it out.

Could be worse, could be raining.
