Varying header images

Hi Sakin, I'm having an issue figuring out how to work with the featured image from page to page. I have a black and white yoga featured header image that I have on the home page, but it currently shows up on the blog page as well. I would like the blog page image to be a different, but when I go to Pages>Blog>Featured image (in the lower right hand corner) and enter an image, it doesn't show up (The image from the home page shows up instead). When in the "Blog" page backend, I have "Featured Image" selected under "Single Page/Post Image Layout". I have the "Header Feature Image Options" enabled. Thanks in advance for your help. Abby
