I did not add an image to my post. Why is a cover image/thumbnail being shown?

If you have not added an image to your post, Superblog generates a random thumbnail image to maintain design harmony. It is only displayed wherever a thumbnail is required but not in your actual post’s content.

Superblog picks the first image of the post as the thumbnail automatically.
