Hi,
The issue is that some images on your site are loading over HTTP while others are loading over HTTPS, which prevents the browser from rendering your images correctly.
Please install the SSL Insecure Content Fixer plugin and follow the instructions in the documentation at this link to resolve the issue: https://wordpress.org/plugins/ssl-insecure-content-fixer/
