I got my response to the reconsideration request - no penalties found.
That means, to me, that image search is not looked into by the spam team since it would have taken two seconds to know that this item belongs in a schoolyard and not on an explicit setting.
I still have not received a response, or the typical acknowledgment Google gives, while using the image reconsideration form linked above. I believe it's an outdated feature since Google doesn't really link to that page from anywhere and the webmaster forum post I found it in is quite old.
I'm out of luck on images it looks like.
Perhaps I should round up a series of extremely mundane, ordinary images that Google images has listed as explicit and make a parody post about Google, the company who wants glasses to see the world on everyone when even a potato peeler is too explicit in their eyes :)
