Alt Text
If an image is strictly decorative, alt text is not necessary. Otherwise, alt text can be added by going to the Media Library, choosing the image, adding the Alt Text in the field in the right column, and clicking the X at top right.

Note: A report with zero results is most likely unattainable. Focus should be on the items labeled “Issue” before “Needs Review”. If an object has a background image or a transparency, the scan can’t parse it and will return a “Needs Review” even if it’s okay.
