You can serve image creatives by assigning them to display line items. Below are the most common requirements and best practices for image creatives to serve on various exchanges. Please follow IAB guidelines.
Best practices
Use high quality images
To make sure image creatives look great on any device, including high-density Retina displays, you can upload image assets that are up to twice the dimensions of your creative. Display & Video 360 will scale down the image based on the resolution of the device where it serves. Display & Video 360 will only scale the image into sizes with the same aspect ratio as the original asset.
To make sure a 300 × 250 creative looks great on screens with higher pixel density, upload a 600 × 500 image and select 300 × 250 as the creative size.
