Hi Stonecherub,
I have written some instructions for you and am attaching them along with a wee test project. Mind you, with Image Mapper 'out of the box' you cannot make images pop up. For that you will need 3rd party scripts, and maybe Eric or Twinstream can explain that process to you.
You can, though, have text pop up when hovering over a sensitive area. In the example project I made a 'page2' in order to show you how to link to a local page. I also linked to an image, and of course to a different site. You can, if you like, have a default page/site opening if someone clicks outside the sensitive spots. I didn't do that, because it might cause annoyance for users.
As I'm saying in the instruction file, I don't recommend using folders for anything pertaining to the image map and the files that can be navigated to within the image map. You appear to be a bit uncertain about correct paths, therefore it's best to keep it as simple as possible.
I hope it helps
