Thank you!Did you manage to remove it? If not, just right click the image itself and press "view image", get the filename and search for it in the Edit HTML window. Then delete the file link from the code, such as (example) https://i.imgur.com/ZEuzUD4.png. Either that, or as well as the file itself, just take out all the coding associated with the link to keep the code clean.
Thank you!
