Funny that you would test the header image first. We've managed to do partial updates for most content on the pages, but right now we still do a full reload (window.location.reload(true), for you DOM junkies) for image replacements. We haven't nailed down the pricing structure yet, but we will be announcing it very soon, and we'll definitely have a free version. Thanks for the feedback!
