Update Header Button Deleted Uploaded Image! Help!

Hi,

I uploaded an image for my banner and everything was gravy, then I deleted the text that was on there and clicked “Update Header” now my image won’t show up even though the code is the exact same!

Someone else had this exact same problem and describe it in better detail here: http://wordpress.org/support/topic/181378?replies=4#post-832027

Please can someone help me, I am at a complete loss!

Thanks : )
