Advanced listing images gallery doesn't work by me.
volvoclassics .nl
No gallery but only some photos.
These open in a new window.
Back is not possible, only previous page.
Can I change this?

Sorry what is advanced gallery?

I read somewhere that this is new with the Zeta Osclass Theme.
I could be wrong, let's call it photo display.
There are photos included in the listing.
If I hold the mouse over the main photo, a hand appears, but the photo does not open in a new window.
No photo gallery opens that I would like.

It should not open in new window.
Looking on Zeta demo, it should open lightgallery:
