From step 3 in Predict Employee Resignation with Google Forms
Open your survey from Drive by double clicking on it. Google Forms gives you several ways to customize the look of the survey.
Simplest: Pick a color. You can simply choose a color from the palette.
Stock image: Google provides several stock images you can use for the header if you like. After clicking the palette, as in the step above, select the bottom right circle with the image icon inside it. In the next window that opens choose a stock image.
Branded: To use your own image, choose “Upload photos” at bottom right in the image window, and upload the image you want to use. You’ll be given an opportunity to crop it to fit.
