I haven't touched my blog in a couple of months and just went back and the header logo is showing either as just a link, or as a broken missing graphic icon. It should be full width about the same size as the header below it.
http://www.audiolink.com/itspeaks
Upper left below the category menu and above the black and white header graphic.
It has the audiolink/itspeaks logo and the title. The entire thing is clickable to go to our main website, not to the blog homepage.
