How do I check for valid images paths in jquery script? They aren't showing up

I'm trying to use a zoom plugin for interactive maps

I put everything into the site and as far as I can tell the scripts are all working. There are no console errors so I'm guessing the problem is that the image paths are not correct because nothing except the containing div is showing up. Looking at it through firebug all I can see is the containing div and referenced css. . . Can someone tell me 1. what开发者_StackOverflow can I use to diagnose this? and 2. Why isn't anything showing up?

My page is here

The first thing I noticed was this error in firebug:

$("#map").zoommap is not a function

And to me, it looks like the map is the only thing not showing up.

You can use a HTTP traffic tool to figure out if the images are requested and served.
