Hi OpenType,
In my case, it will improve the loading speed a lot if I can lazyload the background images on my database. Check this catalog of observable deep sky objects by month, until the last image is loaded the pages does not finish loading, with a huge speed penalty.

I'm using your products on my site on several databases, so improvement can be considered important. Looking forward to hear your thoughts.
