Why aren't images displaying on mobile for my main page?

[DRP996]

Hi, was wanting some help.

All images load fine, but my main page the blocks don't load the images on iphones, but only show the text.

Even on the preview it looks as its designed to work this way.

Im sure somewhere in the CSS its hidden somewhere to hide images on iphones, does anyone know where to look and what to look for, just a rough idea and ill figure it out.

Thanks alot
