Images not loading on main url

I have a rather annoying problem.

On the main url images do not load (www.zammap.com/prettylittlethings)
but if you click on any link or load directly from the server url (http://pammaz.freehostia.com/prettylittlethings/)

everything works fine. When online it's no problem, I can hide the ugly url in codes, but on my cards and such I want the nice clean url and I don' want people thinking that my site doesn't work
D:

is there a way to fix this? Or add some sort of redirection code to bring people quickly away from the not worling www url to the freehostia one?

Works fine in Firefox and IE.

I recently added a javascript code that checks the person's cookie so it can "refresh" aka redirect them from the main url to the working one. However I don't know if it works again if you come back the next day
