All alone - shorn of context, without captions - a photograph is neither true nor false.... For truth, properly considered, is about the relationship between language and the world, not about photographs and the world.
Truth and falsity is something that concerns language, it's a property of language.
Language can be used to so many diverse ends. It can be used to clarify and, of course, it can be used to obfuscate, confuse, evade.
