2. Click the "Form Styles" text link at the bottom left of the Preferences window.
3. After that, click the "Advanced Designer" button.
4. In the Form Designer > Design tab, go to Form Cover section and remove the image by clicking the "Remove" button.
5. After doing this, save the form and verify the changes.
