I am trying to use the weserv.nl image proxy service to load the images using their cloud servers, and don't loat the original img src image. It is to late to rewrite the src for all images and I also don't want to use jQuery for this, as my intention is to make the site faster, not slower to load. So what I want is for the img src not to load the original image, instead add a prefix to the src and load the result. Fiddle example is here. The hard part is that the images don't have id or a class assigned.

var items = document.querySelectorAll("div.separator img");
for (var i = items.length; i--;) {
    var img = items[i];
    img.src = img.src.replace(/.*?:\/\//g, "");
    img.src='https://images.weserv.nl?url='+img.src+'&w=120';
}
