Vanilla 2

Hello,
First of all, thanks for this excellent script!!

I have a website and somewhere in there I'm using an iframe to open another .html page, I know iframes are not the best this days but I have to do it that way. I need to open prettyPhoto from the iframe but load prettyPhoto on top of the iframe, like if prettyPhoto were loading from the main html so the black overlay would be on top of the complete page, not just the iframe area.

I really appreciate any help on this.

Thank you.
