How to upload
- 1Campaign Manager 360: open the campaign or the advertiser’s Creatives tab, click New, then Display, name the creative and, for HTML5, set its dimensions.
- 2Click Add asset and choose the ZIP or the image. For HTML5, check the landing pages and click tags, add the backup image in the Creative assets section, then click Save.
- 3For several creatives at once, choose New, then Batch upload, and pick each backup image in the row Optional: Select a backup image.
- 4Display & Video 360: open the advertiser, click Creatives, then New, Upload, HTML5 or image. Drop the file in, choose the serving dimensions or enter the landing page, add the backup image under Backup images and save.
Good to know
- Publishers set their own limits on top of these: an ad server that accepts 9.5 MB does not mean a site will. Sizewright keeps still images within 150 KB.
- Creatives are rejected for an invalid ZIP or more than 100 files, local or session storage, insecure HTTP addresses in the code, a blank render, a click-through that does not reach a working landing page, or anything that looks like a system warning.

Questions about Campaign Manager 360 and DV360
Where does the backup image go?
Beside the ZIP, as its own upload. Campaign Manager 360 and Display & Video 360 both ask for the backup image outside the HTML5 ZIP, at the creative’s size, and Sizewright’s package puts it there.
Which ZIP limit is right, 9.5 MB or 10 MB?
Google’s own pages disagree: one says 9.5 MB, another 10 MB. Staying under 9.5 MB satisfies both, and Sizewright holds its Campaign Manager 360 package to 9.5 MB.
Does the click tag work in both?
Yes. The package declares a readable clickTag variable, as both platforms ask, and Sizewright checks it in every file before the download is offered.
