In the back-end editor, no apparent option available or default config to make the selected image the link rather than posting the url aside the image. This format makes no sense...the image should be the link or only the url. Option available in editor turns off the image but does not work properly when image set to 'on'. Result of current format distorts the image in favor of showing the url in the same 'div'. See extensive notes in the screen capture.
If I created this in Dreamweaver, I would consider the link appearing aside the image, improper HTML - see
