Hm. I'm a bit divided on this. I think for example that someone should be able to read about chan/underage without having to load underage/chan pictures. However I think to expand the image warning templates to anything NSFW is too far. I guess my view is that in general the wiki can be considered as not suitable for discrete work diversion. For artist pages, maybe if much of their work is explicit a warning at the top or something would be enough? I mean, if the gallery was below the first screen area of a typical screen size, and there was a warning there, then you wouldn't have the annoyance of having to click on two dozen images that are all explicit because the artist only does tentaclerape or something.
