Blogger coding fix problem

My blog needs some repair. Something in the code will not allow me to make posts.I want to keep the basic structure of the blog but want the coding fixed so I can make posts. I believe the problem is that one of the pictures on the blog may be taking up space and overriding the coding. [login to view URL] instructions on how to fix this is not clear to me; I've been referred to read their instructions, but everything I've tried doesn't work.
