Welcome to the Community! From the App switcher, you'll want to go into the Author app, select the course, and edit. The specified item was not found. Select the slide and you should be able to select the image, similar to in Word, and delete it with a backspace or delete. I'm really good at accidentally deleting images on slides, so hopefully this answers your question. If not, please provide some more info so we can help out.
