Scott,
When I post a picture of a document or a part, I make sure I also post the source. I don't claim that it is anything other than what it is, it is just another possible piece of the puzzle. It is up to the individual to decide if it fits their puzzle or if they should continue to look for other pieces.
No one should take any single source as gospel, that's why people ask questions on forums like this one. It is up to each person to decide, through research, what is correct for themselves.
Unfortunately there are usually more opinions than facts.
