It seems like you are serving a couple dozen images from Amazon S3.
While S3 is great for hosting assets, it seems rather slow for serving assets. I think one of the reasons the images load so slowly is because S3 uses HTTP 1.1 which, unlike HTTP 2, doesn't support serving multiple requests in parallel. This means the browser can't start loading all images at once, but has to wait for image 1 to be finished, before it can download image 2, etc, etc.
Full disclosure: I'm not 100% sure that's the correct technical explanation, but based on my limited knowledge on the topic that's my best guess.
Okay, so what is the solution? Add a CDN like Amazon CloudFront to the mix. CDNs are optimized for serving assets like these. You will still host the images on S3, but let Amazon CloudFront take care of serving them to the browser.
