Lofesa commented on issue #2051: URL: https://github.com/apache/incubator-pagespeed-mod/issues/2051#issuecomment-729877988
Hi My 2 cents.... PSI can´t detect lazyloaded images by timings but classes and attributes, if you make your site put attribute `loading=lazy` it will detect as lazyloaded. This attribute is the native lazyload for bronwsers (mainly chrome and firefox). I have no tested how it work with pagespeed. I think PSI uses the class lazyload or related to this word. If none of these are present can´t detect the image is lazyloaded. Anyway... if I remember the module has a list of bot UA string, or search for "bot" in it. PSI no more has the word bot in their UA, it uses "Ligthouse" ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
