All ads on Facebook need to have an image. Adding a relevant image of your product or service can be one of the most powerful factors in determining the success of your ads. Take a look at the Facebook Ads Guide for resources on suggested image sizes and more.

If you're advertising a Page, app or event that already has an image associated with it, you may see that as the default image for your ad. You can use the default image or add a new image to appear as part of your ad.

Learn more about the types of images that you can use in your ads by visiting the Advertising Policies page.
