Latest News Blog Thumbnails Don't Show

Upon first loading the website, scroll down to latest news section and none of the blog posts image thumbnails show up. If I reload the page they *usually* show back up.

Upon first loading the blog page, *some* of the blog post image thumbnails show up and *some* do not. They’re all done exactly the same, not sure what is happening. When I reload the blog page, *some* images show back up but others go away.

On mobile, I cannot get the headshot images from Testimonials section to show up. Also the latest news section doesn’t show thumbnail images, even after reloading the page.
