    Provides lazy loaded image support via the Lazysizes

    A zero query method for per user-group lazy loading of the [img] and [attach] tags in threads and conversations with adjustable distance before images are loaded.

    Uses a noscript tag around the original img tag.

    Supports the add-on [Tinhte] Image Attachment Optimization & CDN Support .

    Option to force lazy loading of contents in a spoiler tag.


    Adds the permission:
    • Enable Lazy Load Images
    For "Forum Permissions" and "Conversation Permissions" sections.

    • Enable Outside threads/Conversations
      • permits the lazy loading bbcode injection to run outside of those contexts. Inside those context it will still respect permissions.
    • Force Lazy Loaded Spoiler

    Unveil effects
    Add styling to your theme for the classes: lazyload, lazyloading, lazyloaded.

    Been running this for several weeks, and have had 0 complaints which is quite remarkable on a board our size. Image-heavy threads load faster, and images load as needed instead of all at once. Admin options make addon very flexible. Thanks Xon!
