My blog has a header picture showing its name. But for some reason exactly one post shows a picture in the header which is actually used within the post itself.
I don't even know how I would acomplish such feat if I wanted - given that the header code as far as I know is included from header.php and hence keeps the same references in every single post...
How do I find out what the reason is, so I can change the header image back to the right one !?
