Problem: When the bot sends images in Feishu chat, images are delivered as file attachments that require downloading. Users cannot see images directly in the chat on mobile or desktop. Expected behavior: Images should be sent as inline Feishu message type image, so they display directly in the chat without requiring a download. Current behavior:

  • Bot sends image → appears as a file attachment in Feishu
  • User must click to download and open to view
  • Not visible inline in the chat Environment:
  • Platform: Feishu (飞书)
  • Channel: iOS/Android mobile app
  • OpenClaw version: 2026.3.13

Problem to solve

When the bot sends images in Feishu chat, images are delivered as file attachments that require downloading. Users cannot see images directly in the chat on mobile or desktop. This creates a poor user experience.

Proposed solution

Use Feishu's image message type (image) instead of file attachment type when sending images. This will allow images to display inline directly in the chat without requiring a download.

Guidance

  • Verify that the bot's configuration is set to use the correct message type for images.
  • Check the Feishu API documentation for any specific requirements or restrictions on sending images as inline messages.
  • Test the updated bot configuration with a small group of users to ensure images are displayed correctly before rolling out the change to all users.
