function includeImage(url, target) {
    console.log('apiunit / image / ', url);

console.log looks like debug code. Are you sure you do not want to remove it?

    var el = new E(target);

The variable E seems to be never declared. If this is a global, consider adding a /** global: E */ comment.

    var elmnt = el.first();

    let img = new Image;

The variable Image seems to be never declared. If this is a global, consider adding a /** global: Image */ comment.

    img.onload = function () {
        console.log("Including IMG:", url);

console.log looks like debug code. Are you sure you do not want to remove it?

        elmnt.appendChild(img);
    };
    img.src = url;  // erst nach dem Event Listener!

    // var image = document.images[0];
    // var downloadingImage = new Image();
    // downloadingImage.onload = function () {
    //     image.src = this.src;
    // };
    // downloadingImage.src = url;
