I had the same issue about a year and a half ago. At that time Instructure told me I could not revert to "no image" and have it inherit the parent catalog's image again. I had to download the image(s) I wanted the subcatalog to "inherit" then upload them into the subcatalog.
Not sure if this has changed since then, but I don't see an obvious way to revert to no/default image. It would be helpful, though.
I found a solution --- if you inspect the page and you have the image on another subcatalog you can save the image to your desktop and then use photoshop to fix the size dimensions to make it fit properly.
Jessica,
