Add Parallax to Widget

I add the [dd-parallax img=”image.png” height=”600″ speed=”3″ z-index=”-100″ mobile=”image.png”][/dd-parallax] to widget but the image is not display.

If I ll add the above code to the page the image and parallex effect is displayed normally.

Can I add to the widget? If yes how?

P.S. Theme is custom.
