Lightbox doesn’t work after copy gallery (javascript)

Hi,

sorry for my bad english.

I copy a content of a container in another container. The content contains a wordpress-gallery. I use document.getElementById(xxx).innerHTML. All works fine.

But the lightbox does not work with the copy of the gallery. After clicking on a picture only the url of the image is loading, no lightbox. The other galleries, as well as the original source gallery, works fine.

I read somewhere that lightbox after loading the page “registered” ( ? ) all images? And I have to start this function after copying again? How?

Thanks for your help!
