At the time of writing, it's this: https://commons.m.wikimedia.org/wiki/File:Woman_at_Lover%27s...

Which is close to what I would've guessed by picking a high population density area, and a likely location and candidate for a decent portait photo on a wildly popular wiki.

Still not sure why the top was edited from red to grey.

Perfect example: English Wikipedia has bikeshedded lead images of this kind ad nauseum over these two decades, with many times more text written in discussions of this than in the articles themselves. The current image for [[woman]] was chosen last year in an RfC that ended with a rare counted vote.¹ This prompted a re-debate of [[human]]² that trailed off in dissastisfaction toward the only established guideline in the area, which forbids montages. That, in turn was last affirmed by a series of debates in 2015/2016.³

Yeah, for starters one should at least try to provide a coherent operational definition of “bias”.
