Hey @zenyogi, good questions! As a general rule, you may use text in an iconic way such as a logo or product name related to the course. I'd suggest, however, you reach out to policy@udemy.com for more details or specifics about your individual situation. We use course images for all onsite/mobile "course cards." If your course appears in Search, in a recommendation unit, in a Frequently Bought Together carousel, etc., it will display your course image. We may also use your course image in offsite advertising. Hope this helps!
