I resized the 2011 Theme Header image on my blog NJN Network.
That works fine along with the Upper Menu for Twenty Eleven plugin.
However, now images from the posts are replacing the header image on Single Post pages.
It used to happen if there was a photograph larger than 1000px in a story. Now it happens all the time since the header is 273px x 35 px
How do I fix that? Thanks for any assistance. Cheers.
