Image is to restore the system to an existing drive in most cases though restoring to a new drive works well also.
Clone is basically for swapping out a defective drive and replacing it with the clone. No restore required. If I were to clone a drive I would use the same size drive as the original.
I had never cloned before but I've used Macrium imaging many, many times successfully. I didn't realize that when you clone a drive it consumes the entire destination drive therefore wiping out the any images or anything on that drive.
It seems you would need a separate drive for a clone or at least partition a large drive.
I have images on 2 drives and a clone on a third.
