  • BJ Lazy Load wordpress.org/plugins/bj-lazy-load . I am using this plugin but does the concept of lazy loading work on externally hosted images ?

    There's no reason why (the concept of) "lazy loading" can't work with externally hosted images. From the client's perspective there's really no difference in where the image is hosted. However, there could be issues in the way images are pulled in from picasa/flickr and the order in which the page is generated? (Although I think "BJ Lazy Load" can handle this OK.)

  • I don't see why you need lazy loading for images that are hosted externally since it doesn't affect the performance of your website at all. Aug 10, 2014 at 5:38

    @Renuka to answer your question in short. Yes. What Question overflow is hinting to is that since the images are not being served from your domain, their transfer will start in parallel while your theme files are being downloaded and will not slow the page rendering process.

yes, but since these external images come from a 3rd part domain you need to make sure they are not blocking them via some method of cors or hotlink protection.

also add dns prefetch meta for domains you will be pulling from.
