Yandex Direct: What Are Image Ads?

Image ads are image-based adverts that appear on the Yandex Advertising Network. When a user clicks on an image ad, they are taken to the advertiser's website, just like what happens with a text-based ad. Image ads must be less than 120 KB in size; in a JPG, PNG or GIF format; and are charged on a cost-per-click basis.
