In the html code I can see `data-pagespeed-lazy-src` and `data-pagespeed-lazy-srcset` so srcset must be lazyloaded too Maybe more related with your picture element and their non "typical" attributes: `<picture data-alt="" data-default-src=` AFAIK psgespeed don´t recognize the picture element, the only part of the element that pagespeed recognices are the default img atrribute and it is rewrited and lazyloaded, but all the atrributes `source srcset` images are not lazyloaded. You can´t use `ModPagespeedUrlValuedAttribute source srcset image` because there are more than one url. If you can build the module, then you can apply this PR #1929 manually and then can use: `ModPagespeedUrlValuedAttribute source srcset srcset`  ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
