No complete solution! Not working with Visual Composer page builder and others!

  • The plugin uses “the_content” filter only, therefor post thumbnails or other non-content images are not loaded lazily. I suggest adding “post_thumbnail_html” and “get_avatar” filters too.

    In settings you can only select a loading offset between 0 and 100px. This may be sufficient for sites with small images but if you have really large pictures e.g. on photo blogs this is not enough. I changed option generator to values between 0 and 1000 in 50px steps. (We are using 600px offset on our page)

    The plugin does not work together with Visual Composer page builder. Because the plugin registers “the_content” hook with default priority (10) the image replace takes place before Visual Composer has translated its shortcodes to html. Therefor when the callback is executet there are no image tags, yet. I changed this to 11 and now it works.

    Other incompatibilities:
    – No images within LayerSliders.
    – No Images within Owl Caroussel.
    – No images in Instagram Feed.
    – …

    Positive, this plugin is the only one I could find performing “real” lazy loading of images! The images get not shown to the user until the browser completed their loading. Thats why 1 star and not 0.

    I suggest you implement the proposed changes in the next release and fix the slider problems for better compatibility. Then 5 stars!

    Agree with these suggestions, would also note that your minification of unveil + ui.js minifies the imageUnveilload localisation variable to a global variable called ‘t’. This prevents the customisation of the image load threshold.

    Would also recommend options for disabling lazy load based on class, page or specific image.

    1.0.8 allows for customization of the image load threshold with a freeform number input.

    Whilst I appreciate your frustrations with the lack of compatibility with Visual Composer and other plugins, it’s hard to provide a catch-all solution that provides full working functionality with every WordPress plugin out there – and then make sure it works well and remains stable.

    We’ll consider adding these to the Pro version, but for now the free version will focus on images within the main content (or any content processed through the_content filter), with the 1.0.8 option allowing for any threshold number vs. the previous limitation.

    Thanks.
