How do I add an Image to my Public Page Description?

To add more branding to the Opportunity Public Page Managers can add an image that will embed in-line with the rest of the Page description.   

The method is to copy and paste the image URL into the Page description editor.  This can be done by finding the desired image online and then right-clicking it to open the image in its own tab. Doing this will allow you to copy the image URL and then paste it into the editor.
