I have created a gallery of labeled photos using the Image/Video Grid. Is it possible to zoom the photos in the lightbox without them jumping on smartphone display? Customers also want to be able to zoom in the photos to see details. Referenzfotos
What do you mean with jumping?
This happens, when you try to zoom (pinch) the picture in lightbox.Then it jumps uncontrollably on the screen of the iPhone
Hi.
I can see the jumping pics 
Is the 320 layout customized or auto scale?

Is “Autoscale for mobile devices” active?
You find it in the settings (bei “Verschiedenes”).
Mr. F.
