18- Add more metadata from the Djehuty API response.
19
20Limitations:
21
22- This is a temporary workaround until the Presentation API is implemented as part of Djehuty
23- Only images are currently supported (not video/audio)
24- The val needs to do some API requests before producing the manifest and doesn't cache responses
