Fullscreen button for jac-lightbox

[provodnik0]

Hi!
Such is the problem that can not handle more than a week.
There are photos. When you click on the photo from the gallery window opens.
Window used for jak-Lightbox
I'm trying to add a button on the similarity such as the image below, which will expand the window to full screen.
The problem with the script and connecting it to this form.

Thanks in advance!
P.S.
sorry for my english

Hi, I think, for this you should customize directly the JAK javascript but I cannot give any clue advice there as I didn't do such or similar customization in JAK javascript yet
