You should use the html2canvas library for this. Make sure you set allowTaint to true so that it renders the cross-origin images as well. See this JSFiddle for an example.

The html2canvas function returns a promise that provides a <canvas> element which you can put wherever you want to display the rendered image. You can then treat it like you would any other canvas, including right-clicking it to download as an image.
