There are various methods available for adding image URLs into Blueprints for Display ads:

You can use single image URLs if you are wanting to advertise using the same image across multiple accounts. Simply paste the image URL into the Image URL field in your Blueprint. Ensure the URL is publicly accessible for our system to retrieve the image.

Use a Blueprint tag to provide several image URLs to your campaigns. Create a custom Blueprint tag with your image URLs listed on separate lines. Then, copy and paste the tag into the Image URL field in your Blueprint. See the [media-example] Blueprint tag in the example below.

Using an inventory feed is a simple way to keep your images up to date. In a spreadsheet, create a column with a tag name (e.g., image). Input your image URLs into the image column. When you add this data source to Fluency, it will automatically create the Blueprint tag [image]. Copy and paste this tag into the Image URL field in a Blueprint.
