Refreshing remote Image source without flickering (resp. empty image during refresh)

[DerMas]

I have a simple Image that uses a remote source (http://url.to/image.png). The problem is, if I change the image source to another url, the Image will be empty while it is fetching the image from the url (looks like a short flickering).
How can I prevent the image from being empty while loading?

Can I somehow force the Image to keep the old source while image.status equals to Component.loading?

My current way too complicated solution:

@import QtQuick 2.2

Rectangle {
id: container
property int imageVisible: 1
property string initialSource
property int fillmode

color: "transparent"

Image {
    id: image1
    anchors.fill: parent
    fillMode: fillmode
    clip: true
    visible: imageVisible === 1
    source: initialSource
}

Image {
    id: image2
    anchors.fill: parent
    fillMode: fillmode
    clip: true
    visible: imageVisible === 2
}

function setSource(source){
    var imageNew = imageVisible === 1 ? image2 : image1;
    var imageOld = imageVisible === 2 ? image2 : image1;

    imageNew.source = source;

    function finishImage(){
        if(imageNew.status === Component.Ready) {
            imageNew.statusChanged.disconnect(finishImage);
            imageVisible = imageVisible === 1 ? 2 : 1;
        }
    }

    if (imageNew.status === Component.Loading){
        imageNew.statusChanged.connect(finishImage);
    }
    else {
        finishImage();
    }
}

}
