I'm a new wordpress user, and I'm having some trouble with my blog (http://yardsalingtoadventure.wordpress.com/). I have a goofy MS Paint image in my header, but for some reason it's only showing up in IE and Chrome, not in Firefox. Any idea why?
I'm using the Twenty Eleven theme, and I've made 0 changes regarding CSS, if that helps.
The blog I need help with is yardsalingtoadventure.wordpress.com.
