Mobile-Friendly Ads: We recommend using a GIF file format for your ads (since flash is not mobile-friendly). If you submit a flash ad, you also have the option of submitting a static GIF file as a mobile-friendly back-up image. If no back-up image is submitted, we will create one based on your flash ad.
