I'm trying to add a custom header image to the twenty eleven theme. I tried a 1000x288 as jpeg. After seeing strange results I tried png with the oddities remaining the same.
Here's what I did:
* create an image with 1000x288
* upload at theme > design > header
* I get asked to crop and publish the image, despite the help article (http://en.support.wordpress.com/themes/custom-header-image/) stating that, if the uploaded image has the exact size (which is the case here) I should not get asked to crop the image.
* when I check my blog I can see the image for 2 minutes or so, but then it is gone. In chrome I see a broken image (http://cl.ly/0B1x1k0t2B0A1z3X0c3V) in firefox I don't see any image at all. when I go to theme > design > header I still see the correct image
What's going on here? Can someone help me troubleshoot this problem?
The blog I need help with is babdua.wordpress.com.
