When I click in my button Jobs I load an Iframe that contains a page with images form. This Iframe is loaded over the site and the effects is cool. I use a LightBox as complement.

But in my address bar, the result is like www.mysite.com/gallery[0]/4/, for exemple, when I view an image. I have a button that close this iframe, not close, only hidden. 

How can I to make something similar to that and back to www.mysite.com . 

If I put an load site when close the Jobs Iframe, this function ok, but I get reload all page and it is unnecessary

Thanks.
