I won't comment on you know who ;-)

But as for the pictures, its a big problem here. I use them from google searches and add my disclaimer notice at the end purporting fair use but to the letter of the law, I'm not sure it is. I did read this recently

Your use may also be protected under the fair use doctrine if you are using the image for criticism, comment, news reporting, teaching, scholarship, or research.

In theory though, we are earning from their use so its a minefield that needs treading carefully.
