add image to left of title

Hi, trying to add an image to left of title: http://www.gadflymagazine.com

I managed to add one with the following code inserted into the stylesheet:

#header id a {
padding-left: 52px;
background: url(http://www.gadflymagazine.com/wp-content/uploads/2014/02/gadfly-logo-07.gif)  no-repeat;
background-position: left;
}

But it only adds to it the homepage, not on pages/posts. So I added the same code again, but with “id” replaced by “div” – that worked for pages/posts, but also added the image to the nav buttons.

Any ideas? Thanks!
