Hello there,
We are not using lazyload or another JS script to load the images.
Unfortunately Google AMP does not support background images out of the box. You will need to override the template a bit. The <img tag's src attribute needs to be the image (use CSS to hide it) instead of the transparent.gif file.
Google thinks that the image is the transparent.gif instead of the actual file which is rendered as a background image.
