Javascript (or jquery) to get every image tag of a textarea value

So suppose I have a textarea with a value of this:

<p>..random content..</p>
<img src="myimage1.jpg" />
<p>..random content..</p>
<img src="myimage2.png" />
<p>..random content..</p>

I want to check every img tag occurences and store the src in an array. Something like this:

function img_find() {
    var imgs = // the result of the checking of the textarea
    var imgSrcs = [];

    for (var i = 0; i < imgs.length; i++) {
        imgSrcs.push(imgs[i].src);
    }

    return imgSrcs;
}

How do I achieve this?
