Mangled image paths showing up when using Upload feature within theme options

I’m using a theme by Elegant Themes called eStore, and it works fine on my basic install at the root level.

I’ve got a development site running inside another directory and have that WordPress install set up for Multi-site, with another installation of the eStore theme. From here, when I add images to the posts that control the Home Page Image Slider, an unusual thing happens to the image paths. I’m either getting a missing ‘/’ or the image path is being prefixed with what I think might be a root server path.

What should be this:src=””

Is showing up like this: src=”/home/content/82/8284682/html/shop//wp-content/uploads/2011/08/slider2_bg1-104466_109x109.jpg”

I’ve uninstalled and reinstalled the theme, but I don’t fully understand how those image paths get created, so I don’t know where to look to get rid of the “/home/content/82/8284682/html/shop/”.

Can someone suggest something? Thank you very much.
