It may be that more controversial images provoke more
meta-discussion,
with more links to them as a result (from talkpages, deletion
discussions, etc) and so are more likely to appear "popular" to the
search system, but that's just a guess.
Hm, Lucene Streisand effect.

I guess that has something to do with the name of the
images. The sexual
image has the name of File:Sexuality *pearl necklace* small.png
<http://commons.wikimedia.org/wiki/File:Sexuality_pearl_necklace_small.png>
so, would be obvious to be one of the first results if
you are looking
for *pearl necklace*.
Looks like there are 248 exact file matches.

I see that the first image doesn't use information template, perhaps
descriptions within templates are treated differently? Could be a wrong
assumption based on how infoboxes work on Wikipedia. (Just more
imaginative speculations...)
