Targeting images outside the document

Transform can now describe remote images. If the source image is available on an HTTPS URL outside of the target document, it is possible to get a description for it using the image-description operation type with imageUrl.

Example:

client.agent.action.transform({
  schemaId,
  documentId,
  instruction: 'describe the image in great detail',
  target: [
    {
      path: ['imageDescription'],
      operation: {
        type: 'image-description',
        imageUrl: 'https://www.sanity.io/static/images/favicons/android-icon-192x192.png?v=2',
      },
    },
  ],
})
