I've been working with main and mobile in variances. When I click on Preview Website it only shows me the main side. Is there a way I can get it to show me the mobile side?

I did a little test with the mobile side by making a picture a pop-up x 500pix and it will not pop-up when viewing it in the PW mode on mobile side. I then switched over to the main side and double-click on the picture and it still would not pop up. I checked all the settings in images on the mobile side and the pop-up checkbox was checked but it was not checked on the main side.
