Google Calendar JavaScript API Throwing an Error

First things First here is a link to my web site: boba.dyndns-server.com/Test/index.html.

After I click "Submit Courses", chnage the drop down from ignore to Specifie开发者_如何转开发d, and click generate. It throws the error

Uncaught Error: An image of the same domain is required on this page for authenticated reads and all writes.

This error is thrown from line 215 in this file Can anyone explain to me what is causing this?

You must have an image on your page.

"It means that your page needs to have at least one image (<img 
src="..." />) that's hosted off of your domain. It doesn't matter 
what, there just needs to be at least one image. 
It's a strange requirement, but that's part of the mechanism we use to 
bypass the same-origin policy.
