Link Shadow Box? JCE/NoNumbers?

hi Si Team

The Blog Cover Image opens in a shadow box.
Images on the Blog open in a shadow box if I set this up correctly.
I can set up an image to go to a link and on a new page if necessary.

But as far as I can see within EB there is no way of opening a shadow box if I click on a link?

I actually have the JCE Media Manager (NoNumbers have something similar) but see no way of accessing this from the EB 5 interface.
Is there a way to get to the JCE Media Box Editor/NoNumbers Modals from EB5 so that I can implement shadow boxes?
Here is the Blog post I am talking about:

Last resort is there a way to switch from the EB5 Editor to a HTML editor.
I have some one who is prepared to walk me through inserting code.
Again as a last resort.

thanks

Paul
