Facebook's Preferential News Feed Exposure

Facebook has made it clear that they are going to give preferential news feed exposure to people that paste in a link and allow Facebook to pull in the image. But anybody who administers a page could go ahead and say, let's go ahead and alter that image and upload an image of our own. That's still legit. If we decide to upload an image as an attachment is what I hear you saying, right? Like a photograph, for example, that will get less preferential treatment according to Facebook in the long run. It might take a little while for that to take effect. You don't want to completely abandon posting photos with links in there.
