| # MSC4221: Room Banners | ||
|
|
||
| This proposal adds room banners to Matrix, similar to the way Discord has guild banners. | ||

There was a problem hiding this comment. I wonder how this would render in a Matrix client today. Discord has banners for it's guilds but they only really show up on invite to the guild and in the top right of the client when viewing the guild. They're not really tied to individual channels. For Matrix rooms, where would this go? Obviously I don't expect the spec to start designing the client but I fear there isn't enough information about how this should be presented to the user. Would this be displayed on invite? (in which case there needs to be recommendations for There was a problem hiding this comment. I would think that banners should be above room info. |

| ## Proposal | ||
|
|
||
| Matrix has ways to add room avatars, but those are limited to a 1:1 aspect ratio. This proposal adds banners to rooms, which are a 16:9 aspect ratio. | ||
| A banner state event should have the type `m.room.banner` and the content should contain the `url` in `mxc://` format. | ||
| Example event: | ||
| ```json | ||
| { | ||
| "type": "m.room.banner", | ||
| "sender": "@everypizza:chat.blahaj.zone", | ||
| "content": { | ||
| "info": { | ||
| "mimetype": "image/jpeg" | ||
| }, | ||
| "url": "mxc://…/…" | ||
| }, | ||
| … | ||
| } | ||

| ## Potential issues | ||
|
|
||
| A malicious user could upload a banner with explicit or illegal content. A future MSC may provide a way to mark room pictures or banners as sensitive using [MSC4193](http://github.com/matrix-org/matrix-spec-proposals/pull/4193). | ||

There was a problem hiding this comment. Some concerns about having reasonable fallbacks here. Not every client would be able to display a banner (and I'm not sure every user is going to want to be confronted with a banner in their client), so I think there should be some way to fallback to textual representation of the banner. I don't know how common it is for banners to contain actual information, usually they seem to be more decorative? There was a problem hiding this comment. By "sensitive content", I mean things that would commonly have a content warning on platforms like the Fediverse such as food, lewd stuff, politics, etc. There was a problem hiding this comment. Sorry, I commented a line below where I meant to :). This was a separate concern. There was a problem hiding this comment.
sorry for offtopic, but why food is sensitive content? There was a problem hiding this comment.
@officialdakari Propably because Eating Disorder. It shouldn't be required, but some people on Fediverse go overboard with it. /offtopic |

| ## Unstable prefix | ||

|
||
| While this MSC is unstable, clients wanting to implement this should use `page.codeberg.everypizza.room.banner` instead of `m.room.banner`. | ||
