There are people who do deliberately publish images of themselves under a permissive licence. Sometimes seen with photos for specific topics on Wikipedia (published on Wikimedia Commons). I can only guess at their motivations, but there seem to be a good deal of exhibitionists and copyleft idealists in that group. If a photo is used on Wikipedia with the licence you need, there is a solid chance the vetting process was done thoroughly enough. For photos of a person this would the first place to look for me.
