Photos not showing in IE

On my Classified listing pages, the photos for the listing and the thumbnails do not show up in Internet Explorer. The images are there in Firefox & Chrome but not IE. Can anyone provide any insight as to how to fix this issue?

Link to listings page: https://dragboatcity.com/new/listing-category/boats-for-sale/
Click on one of the listings in IE and photos do not appear at all.

Here’s an example link:
