One thing to remember is that Wikipedia prefers free photographs. Non-free photographs can be used but the preference is towards free ones. The availability of free photographs varies a lot. Often the best source for politicians is when they meet the US President, since photos by the White House photographer (and other federal employees) are public Domain (simplification). eg the Photograph on King Charles' Wikipedia page is a White House photo. https://en.wikipedia.org/wiki/Charles_III#/media/File:Charles,_Prince_of_Wales_in_2021_(cropped)_(3).jpg https://en.wikipedia.org/wiki/Charles_III#/media/File:Charle... Apart from the US Government it is often hard to get "free" photographs from earlier than 2000. Cameras were less common and those that took photographs were/are not uploading them to the Internet under a free license (and they won't age into Public Domain for many years).
