 *Image 2 - I think the most prominent image for a politician should be a portrait; others could of course be used below. Image 6 may be an official portrait, but it looks like it could easily have been taken impromptu in a hallway as she was on her way to a meeting. It also suffers from a shortage of contrast or saturation or something, and would need some skilled touch-up. While conventional wikiwisdom seems to favor more recent photos, I question that in this case. The article is about her entire life and career, not about the past few years, so recency seems far less important than it might be for someone who became notable, say, three years ago. ―  "
