So much this, blogs add an image for the sake of having an image. At this point it would be much better to just have a random dog or a cat pic, it is as relevant to your blog post as your random generated thing, but I'd prefer seeing a random happy pup.
And if you generated a pic I suppose you also generated your post, so I'm way less likely to pay attention to it.
