Files and images

Share files from the composer when your server provides file storage. These screenshots use sample members and a flower arrangement.

Share files

1. Use the attachment menu, drop files onto chat, or paste an image into the composer.
2. Check the staged thumbnails above the composer. Add more files with +, or remove a tile you do not want to send.
3. Expand the share options. Choose visibility, compressed or full image quality, and an expiry where the server supports it.
4. Add a message if you want, then Send. The options apply to the whole batch of attachments.

Visibility

• This channel / This conversation: access is restricted to the conversation’s audience through the server’s authenticated file service.
• Anyone with the link: the link can be used outside the conversation.
• Password: set a password before sending and give it to recipients separately.

Availability depends on server permissions. Locked choices explain why they cannot be used. A password share cannot be sent until it has a password.

Quality and expiry

Photos can offer Compressed and Full quality with their sizes. Compression choices appear only when there is a smaller image copy to use. Other files keep their original bytes.

Where the server supports timed deletion, choose a lifetime for the share. Expired attachments display an unavailable message. Retention and upload limits come from the server; see File storage.

Open and download

Images display as a gallery; select one to view it at full size. Audio and video can have inline players. Other attachments show their filename and size. Use the card’s download or open control. Password shares ask for the password when needed.

Deleting a chat message and deleting its stored file are separate operations. File-management actions depend on the server and your permissions.

If file storage is unavailable, the composer reports that restriction. Small inline images may still work within the server’s message limits.
