I don't want to cause an argument here, because I completely agree with your point of view; however, I find it slightly ironic that a post about the importance of original content uses another photographer's picture:

Royalty-free images are fair game, but I'm assuming you don't have rights to use Scott Applewhite's photo? We can't forget that original content applies to photography as well. I use royalty-free images in my posts to avoid any conflict. Something to keep in mind.
