The headline seems a little sensationalist. Even the blog in question released a statement saying it was obvious that they were in violation.
Arguments in favor of violating copyrights are getting old. It's easier than ever before to create images, music, and movies. If you don't want to play by the copyright rules that content creators have opted into, create your own works and release them public domain, and get other people to do so, and then instead of breaking the law, you can legally enjoy public domain stuff. Like in this case, I'm sure there are millions of similar images released public domain or creative commons, so why pick the image that has a license fee?
