    In your case, this would suffice:

    <img src = "screenshot.jpeg" width ="100%" />

    Of course this will only do what you want if body is the same size as the viewport. This basically tells the browser that the img should be just as big as its parent (in this case the body).

    Note: Javascript does not work the way you expect it. <script> is an HTML element, that lets you embed scripts (Javascript mostly) into your document. You cannot change the HTML source with Javascript on the client side (like you can with PHP, Python, etc. on the server side). You can modify the DOM though.
