Percy, I just read back through this discussion and peeked at the image in question (looks like my little sister, actually), and there's something I wonder about.
In the past, I had image links removed by a moderator due to two concerns: copyright issues and the questionable courtesy of cramping another site's bandwidth. As I recall, the standard suggested to me (by jar and Moose) was that all image links should be to an image repository of my own.
It seems to me that HAWG's image link should be removed on those grounds alone: it doesn't pass the tests above, so questions of censorship, etc., don't really get a chance to apply.
Maybe his link could be translated into text--"naked lady with finger"--or something equally relevant to our debate.
