How do I take the source code of a Form Widget and turn that form into a JPG pic

Hello!

I created a flyer widget through MowPop’s plugin to promote my business, but when I right click and save the image, it only saves the background of the flyer and cuts out all of the content. How do I use the source code of the flyer wiget as a way to make it a jpg image where it shoes the whole flyer? Thanks!
