ImageReferenceBlock

An image, referenced by URL rather than embedded in the message.

You can point url at any image the end user's browser can reach.

Freeday-hosted URLs expire seven days after upload. Treat the url on an older message as potentially dead — an image replayed from channel history more than a week after it was sent will no longer load. Upload the image again to get a working link.
- filename
  Type: string
  required
  
  Filename of the image, used as its alt text. Freeday-hosted uploads return a generated name (a UUID plus the original extension), not the name the user's file had.
- id
  Type: string
  required
  
  Unique block identifier
- type
  enum
  const:
  image_reference
  required
  
  Block type discriminator
- url
  Type: stringFormat: uri
  required
  
  URL the image is served from. For Freeday-hosted uploads this is a signed URL that stops working seven days after the upload.
