So on my blog page, I have the giant area that is blank before my post and I cannot figure out how to remove it, or fill it with an image or what. It has something to do with categories but I've fiddled with that and still nothing.
I have seen that here http://theseedsofwrath.com/the-warnings-of-corporate-run-government/ you have a small picture in your post. Try to set that up as featured image for that post.
If it does not work try to replace it with an image of 777 / 437 pixels (in the post and in the featured image section)
I hope this will help you.
