OP, this is what you are looking for. Someone correct me if I'm wrong, but the only ways to do this and keep the look of your site uniform are to 1) not display featured images for posts or 2) create featured images for each post. Otherwise you will have some posts with images and some with not. And the ones with may be of different dimensions, look, and quality.Do you mean that you want a blog with "syndicated content" like an RSS feed?
