You can embed a PDF in an image and in a similar fashion, you can link the uploaded image to an external link. To do so:
- Hover over the image in the text editor. A Cogwheel Icon would show.
- Click on the Cogwheel Icon. The Edit Image pop up would appear.
- Enter the URL that you would like to embed.
- Finally click outside the text editor until you see the borders turn blue to save the changes you made.
