NIP-68 ====== Picture-first feeds ------------------- `draft` `optional` This NIP defines event kind `20` for picture-first clients. Images must be self-contained. They are hosted externally and referenced using `imeta` tags Unlike a `kind 1` event with a pircture attached, Picture events are meant to contain all additional metadata concerning the subject media and to be surfaced in picture-specific clients rather than general micro-blogging clients. The thought is for events of this kind to be referenced in a Instagram/Flickr/Snapshat/9gag like nostr client where the picture itself is at the center of the experience. ## Picture Events Picture events contain a `title` tag and description in the `.content`. They may contain multiple images to be displayed as a single post. ```jsonc { "id": <32-bytes lowercase hex-encoded SHA-256 of the the serialized event data>, "pubkey": <32-bytes lowercase hex-encoded public key of the event creator>, "created_at": , "kind": 20, "content": "", "tags": [ ["title", ""], // Picture Data [ "imeta", "url https://nostr.build/i/my-image.jpg", "m image/jpeg", "blurhash eVF$^OI:${M{o#*0-nNFxakD-?xVM}WEWB%iNKxvR-oetmo#R-aen$", "dim 3024x4032", "alt A scenic photo overlooking the coast of Costa Rica", "x ", "fallback https://nostrcheck.me/alt1.jpg", "fallback https://void.cat/alt1.jpg" ], [ "imeta", "url https://nostr.build/i/my-image2.jpg", "m image/jpeg", "blurhash eVF$^OI:${M{o#*0-nNFxakD-?xVM}WEWB%iNKxvR-oetmo#R-aen$", "dim 3024x4032", "alt Another scenic photo overlooking the coast of Costa Rica", "x ", "fallback https://nostrcheck.me/alt2.jpg", "fallback https://void.cat/alt2.jpg", "annotate-user <32-bytes hex of a pubkey>::" // Tag users in specific locations in the picture ], ["content-warning", ""], // if NSFW // Tagged users ["p", "<32-bytes hex of a pubkey>", ""], ["p", "<32-bytes hex of a pubkey>", ""], // Hashtags ["t", ""], ["t", ""], ] } ``` The `imeta` tag `annotate-user` places a user link in the specific position in the image. Picture events might be used with [NIP-71](71.md)'s kind `34236` to display short vertical videos in the same feed.
