Text-only ads don't contain any photos or videos. Basic Photo ads allow uploading one photo with your ad and display it as a thumbnail on a search and a larger photo on the detail page. Premium Photo Ads ads include the ability to upload more pictures and display above Text or Basic ads. Premium Plus Ads are everything in a Premium Photo ad and more. These ads allow for more photos than the Premium Ad, have an improved template for better appearance, and also display above all other ad types on a relavent search.
