My problem with stock photos is that unless it is clearly a stock image, it can mislead. For example, when looking up information on the solar panels that Jimmy Carter had installed on the White House, the article had a stock photo of a modern photo-voltaic panel. So I was initially confused, as what was described was a solar collector that concentrates the sun's heat to provide hot water for the kitchen. Which makes a lot more sense of why it wasn't re-installed during some roof renovations under Regan (the initial purpose of it was more to inspire the nation, that wouldn't be served much by re-installing it after it had been removed for roof work as the original moment had passed).
