The Images on my Product Pages are not displaying

Hello Friends

The images on my product pages, for my website Chasinunicorns.com are not displaying, unless you actually click on the place where the image should be showing. As of right now I am running a "bulk" image smush process with plugin: "wpsmush from wpmudev" Can you please help me and let me know if there is anything else I can do... to make sure all images are showing and loading properly and timely... Thank you!
