The image doesn't have a face, neck or upper chest?  You can be creative with the thumb to represent your figure without showing the nude bits.  I see it everyday in the galleries. I've seen some extremely artistic thumbnails without any nudity and the full image has plenty of nudity.  Surely the image isn't just the breasts and genitals, there are other parts of the whole figure showing right?  If the image is tagged as nudity then that tells the person that when they click on it, there will be nudity so its not misrepresenting the full image to not show the nude bits in the thumbnail????

I will state again that there were several factors involved in making this change NOT just those that don't care for the t&a in your face thumbnails. And alot of those people DO want to see artistic nudity just not in your face thumbs because the artistic merit of your image surely isn't just the t&a??
