Thank you. That's helpful but raises three new questions: 1) If I add HTML to a section, can I refer to graphics that I have uploaded into the webbuilder system? And if so, 2) how do I refer to them? 3) Is there a way to see (or create) a url to include the graphic in the HTML?
You can publish the image to an unlisted page, access that page in your browser, right click the image and select view image, copy image location, or similar. This would give you the URL for the image, which can be used as the img src in an HTML section.
