Google Chrome extensions - Get images from cache

I am reprogramming a Google Chrome extension, it was able to download an image using the src attribute, but now, the page change the way it shows the image, it use in the src attribute some kind of script that in background changes the image, getting a different image that web page is showing. I can see the image that I need but using "ChromeCacheView" of NIRSOFT, but it's a desktop solution, so it can't help to do it in the Chrome extension.

Someone could help me, please!

This code below is what I'm using now, but as I said already, it can't show me the web page image is showing.

    var xhr = new XMLHttpRequest();
    // I think here is where I need the change Getting this ID from cache
    var kima = $(frame1).contents().find("#ccontrol1");
    xhr.open('GET',kima[0].src,true); 
    // 
    xhr.responseType = 'blob';

    xhr.onload = function(e) {
      if (this.status == 200) {
         var blob = new Blob([this.response], {type: 'image/png'});
         kym_send_image(blob);
         kym_process01();
      }
    };

    xhr.onerror = function (e) {
        window.location.href = url1;
        return;
    };

    xhr.send();

Well you need to use request.fetch,

You could replace your code with this one below

fetch(kima[0].src,{cache : "force-cache"}).then(r => r.blob({type: 'image/jpg'})).then(blob => function_to_catch_blob(blob));

Hope this could help you!
