Playground
Upload through the app. Read from the CDN.
Change the avatar below. The file goes to this app's backend, which checks it and stores it in Sanity. Everything you then see is fetched by your browser straight from cdn.sanity.io.
Enter the demo passcode
Uploads go through an authenticated backend, so the playground needs a session. The passcode is published in the DEV post. A session lasts 24 hours and allows 5 uploads.
Public images only. A Sanity image asset is readable by anyone who has its URL, so AssetLake is for avatars, covers, and other images meant to be seen.
