Eirian is right, the nudity flag doesn't show up in the gallery like it does here in the forums... if you check the box during your upload that says "Nudity" then vistors who have opted not to show nudity when browsing the gallery will not see that thumbnail... I'm not sure what happens if someone is logged in as Guest... it may be set to automatically not show nudity in the gallery... but like I said, I dunno... You could do what I do, and put - Nudity after your title, so that people who do choose to view nudity in the gallery will no as well... people I work with often visit my gallery, and if they're doing it from work, they can avoid the nude images... that's the reason I always add that little tag to my titles... though I think I have more nude pin ups than anything... shrug
