If I'm clicking on publish, its coming "Please add at least one image to your introduction." This means what?

I made my first instructable. Then I clicked on publish button. After that it's coming as I mentioned above. Someone please help me with this.

Drag a picture to the "intro" step.

You don't have a picture on the very first page/step. Add one and you'll be able to publish.
