How to See Slider Images on iPhone

Good day - I am a photographer and enjoy the features of Everest Pro. I have recently noticed that when my site is viewed on an iPhone, the slider images are not visible and there are no images related to my blog post list. It is only when you click on an individual blog post that you then see the image. Unfortunately, my site looks like a text only site on a smartphone rather than the clean photographic site it is designed to reflect. Can you please offer some suggestions or help me identify which settings I need to correct? www.ChipBunnell.com Many thanks! chip
