In Avada 5.8, we introduced Lazy Load for images. This can be enabled under the Performance tab at Avada > Theme Options > Performance. What this does is to only load the images that are visible in the viewport. As the user scrolls and more images come into view, they are then loaded as well. This provides an instant benefit to page load times, as only the initial images in the viewport are loaded.,Where Is Lazy Load Enabled?Lazy Load is enabled in these areas and elements in Avada:
Blog Element – medium, large, grid and masonry
