I recommend reaching out to Airtable support directly (in the app: Help → Contact support). While Airtable staffers do frequent the forum, they prefer to be approached directly with support requests.

This is one (of many) reasons Airtable has not claimed GDPR compliance and isn’t likely to do so in the near future. You’ll need to describe your use case for using Airtable as a CDN for images; there may be a workaround.
