Hi,
I think the problem is that we can’t override the LAZY LOAD.
Normally, you can tell that WordPress lazy-loads an image by checking for the presence of the “loading” attribute with the value set to “lazy” in the image markup. However, in your installation, the “loading” attribute doesn’t exist. Instead, there are multiple attributes related to lazy loading, indicating that lazy loading is controlled by either a plugin or a custom script. These additional attributes include “data-lazy-sizes”, “data-lazy-src”, and “data-ll-status”. Looks like these attributes are added by the WP Rocket plugin.
<img decoding="async" fetchpriority="high" class=".. lazyloaded" data-lazy-sizes="(max-width: 703px) 100vw, 703px" data-lazy-src=black-and-gold-and-blue-art-hanging-on-a-wall.jpg" data-ll-status="loaded">

Best regards,
