With tallacmans sitename you can position your logo and site name in a repeatable area. Dead simple to use, you can put your logo on top, bottom left, or right. You can also have just your site name or just your logo. The logo will be constricted to 50px high so use a small image. There is a custom template called 'unconstrained' that will not scale the image for users that want to override the constriction.
Your sitename and/or logo image will link to your homepage automatically.
