Hi,
we encounter the same issue and been able to narrow down the problem source. It seems that Edge cannot properly execute default transition animation that is set in this slider template – http://www.masterslider.com/template/free-restaurant-slider-horizontal-thumbnails/
When we changed the transition from normal to fade (slider settings->transition settings->transition), everything works fine and every image is viewed properly on Edge.
I hope it helps solve this issue!
Cheers.
