@disabledanarchist @Elizafox you can use #Alt4Me or #AltForMe so people can provide you with image description which you can then copy and edit your post and paste it.
@LunaCottonwood One thing you can do is to reply to your own post with the tag #ALTforMe. People who follow that tag can them come along and reply with a caption. (Original post about this: https://kolektiva.social/@oedipusnj/109371891665923566)
@Curator @PleaseCaption I saw yesterday this toot that proposed the #ALTforMe and #ALTforYou hashtags and I thought it could be useful?
