Fans of danbooru who want to be able to browse in public places can rest easy now; there is now a worksafe version of Danbooru, one of the largest image archives on the net. Safebooru, as it's called, has all the images that danbooru has except for those that are sexually explicit or otherwise unfit for viewing in public places, and has also ditched the explicit ads. There's still some provocative stuff here and there but nothing that's likely to get you in trouble.
Just thought I'd give everyone a heads-up.
