Marker Behavior

I also have an additional question on the map I am working on which can be viewed here: http://www.harrodsfarmllc.com/map/. Is there a way to get the images that pop-up on marker #43. (top left, near the intersection of Quail and Sparrow) to scroll horizontally? Or just have one image in the box which links to a lightbox gallery where you can still see the map below? I don’t want to go to a separate page. I’m not sure if this is possible and what the best approach is. Thanks!

Thanks.
