Open colorbox (Group Images) from iframe to parent

Question

I plan to use Colorbox (http://www.jacklmoore.com/colorbox) in an iframe environment, how can launch the viewer from within an iframe?

Below link is works on iframe content/youtube, but I want using Group images. So it will can click next/prev images. http://blog.svnlabs.com/open-colorbox-from-iframe-to-parent-window/

Is that anyway can solve this?
