pre-loop image

I’m trying to add a static image before the loop on the index page of http://www.boattorow.com/btr

I have tried everything I can think of but the best I got was the image appearing before the content on every single page, I’m pretty frustrated because it seems like such a simple thing to do! If someone could point me in the right direction I’d be so grateful!

The site is running the Platform theme by SideLines which has changed a few of the php files & added more on the editor list, I assume this may be relevant ?!!
