    The thing with LazyLoad is that you're loading extra JavaScript. Now depending on how much stuff you're downloading anyway, this may be insignificant. However, in most cases images will be bigger than the JS anyway, so you should be using it.

    I've noticed that it's not supported with all browsers yet

    Lazy loading means " Load it when I need it " when most of the time scripts are just made with " Load it ".

    So obviously Lazy Load always improve performance (For instance Lazy Load in model when talking about MVC for example)

      This is NOT really true.

      If you have a site with a lot of images and thumbnails ... then it is improving.

      If you have a "normal" website it is not really improving. If it would be an improvement for every website... every website would use it.

      As I said, it makes sense when you have a site like... a wallpaper site or stuff like that.
