You can serve image creatives by assigning them to display line items. Below are the most common requirements and best practices for images on various exchanges.
Best practices
Follow IAB guidelines
Use high quality images
To make sure images look great on any device, including high resolution screens, upload image assets that are up to twice the dimensions of your creative. Display & Video 360 scales images based on the resolution of the device where your ad appears. The image will stay the same shape, even when it's resized to fit different screens.
To make sure a 300 × 250 creative looks great on high resolution screens, upload a 600 × 500 image and select 300 × 250 as the dimensions.
