Answer 1

Ok nothing working to me. Then i replace image url every second because when my DOM updates, the problem is here again. Other solution is only use background style auto include in pages. Nothing is clean.

setInterval(function(){ imageUpdate(); }, 1000);

function imageUpdate() {
    console.log('######imageUpdate');
    var image = document.querySelectorAll("img");
    for (var num = 0; num < image.length; num++) {
        if (stringBeginWith(image[num].src, "http://1.1.1.1/bmi/***yourfoldershere***")) {
            var str=image[num].src;
            var res=str.replace("http://1.1.1.1/bmi/***yourfoldershere***", "");
            image[num].src = res;
            console.log("replace"+str+" by "+res);
            /*
            other solution is to push img src in data-src and push after dom loading all your data-src in your img src
            var data-str=image[num].data-src;
            image[num].src = data-str;
            */
            }
        }
}

function stringEndsWith(string, suffix) {
    return string.indexOf(suffix, string.length - suffix.length) !== -1
}
function stringBeginWith(string, prefix) {
    return string.indexOf(prefix, prefix.length-string.length) !== -1
}
