I don't know. I just bought the issue at a Safeway.
The accompanying article includes quotes from two parents of victims saying that they approve of the release of the photos, hoping it "de-romanticizes" the idea of shooting up your school and killing yourself.
The photos are about what one would expect - not pretty. Harris and Kleybold are sprawled on their sides with blood puddling around their heads. You can see more of Kleybold, and he seems to have more blood showing. Kleybold's gun is on his right side, but he was apparently shot in the left temple (I couldn't tell from the photo becasue his whole head is bloody). The Enquirer alleges that the gun's position, and the fact that Harris' foot is touching Kleybold's elbow, means that Kleybold died first and Harris shot him. I don't know that it proves anything, but I'm no expert on forensics.
