Step 2
Under the bottom-layer background, click Select Image.
Step 3
You can either select a photo from previous uploads or upload a new file.
Step 4
Select the image you want to upload.
Step 5
To enable parallax scrolling for the image, click the button next to fixed. When it is turned on, it is blue.
Step 6
To ensure the photo extends as far as you would like, you may need to increase the size of the blank text box above the photo.
