+A kind `0` event MAY carry `imeta` tags describing the images named by the `picture` and `banner` fields of its stringified JSON content ([NIP-01](01.md), [NIP-24](24.md)). This gives profile images the same `fallback`, `blurhash`, `dim`, `alt`, and other [NIP-94](94.md) fields available to any other attachment.
+
+An `imeta` tag describes a field only when its `url` is exactly equal to that field's value. Tags whose `url` matches neither field SHOULD be ignored.

+Clients SHOULD try the declared `fallback` URLs when the primary URL fails to load.
+
+Since kind `0` is replaceable, clients publishing a new kind `0` SHOULD carry over the `imeta` tags for a `picture` or `banner` that hasn't changed, and drop the tags for images that are no longer in use.
