  • Images that contain inappropriate expression can’t be used. Check our guidelines when you prepare your images.
    Advertisement Editorial Guidelines
  • When using downloaded images, check format and size again along with Advertisement Editorial Guidelines.
  • You can add larger images when the image size and the aspect ratio match. This doesn’t apply to logos and 300x300 sized images.
    Example:
    When the specified size is 640x200 pixel, you can add 1,280x720 pixel images that have the same aspect ratio.
