Lofesa commented on issue #1691: URL: https://github.com/apache/incubator-pagespeed-ngx/issues/1691#issuecomment-639400798
Well... the images from other domains other than your own domain are not touched by pagespeed at all, even not by IPRO, so the images loaded by a javascript from the docs-trans domain can´t be optimized. If the images where loaded by javascript from your own domain, then the images can be optimized by IPRO. Lazyload_images filter add a class to the images and a javascript snipet to do the work, and add a blank image as a placeholder. Lazyload filter takes some hits to work because the filter need some info from images, these info is gatered by the beacons. Basically, pagespeed need to determine if the image is on the viewport or not and then add the class and the javascript, until pagespeed does not determine if the image in in the viewport you can´t see it lazyloaded. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
