Format
Choose the format of the creative. (IMPORTANT: You can only choose among current placement formats created in your account)
When choosing the format, keep in mind that this affects where you will be able to book the creative and essentially the campaign.
Creative source
Link
Use an image from an external link source. Can only be used for display creatives.
Upload
Upload an image from your computer. Max file size is 250 kb.
Waiting
Save the creative without choosing an image. IMPORTANT: Creative will not deliver before an image has been selected, but will be eligible for bookings. If all creatives on a campaign are "Waiting", the campaign will not start delivering.
Preview
Here you will see a preview of the uploaded image, hence a preview of the whole creative if it’s a display creative.
NOTE: If you are setting up a display creative, then the selected format is only a guideline. The system will serve any image that is linked or uploaded. This means that if you select the creative to be with the format “300x250”, but upload an image that is “600x500”, then the system will still serve the image as its full size, 600x500, and how that ad is handled is then up to the given Media’s template and the HTML/CSS surrounding the Placement integration.
