Problem

When the assistant generates or reads an image file (PNG/JPG), the image is not displayed directly in the webchat interface. Instead, users see either:

• A broken/empty response
• Need to manually open the file path in the filesystem

This happens with:

• read tool on image files
• message tool with image attachments
• Screenshots and generated images

Expected Behavior

Images should render inline in webchat, similar to how they work in other channels (Discord, Telegram, Slack).

Current Workaround

Users must:

1. Open file path directly: \\wsl$\Ubuntu\home\wang\.openclaw\...
2. Use a local HTTP server and open in browser
3. Switch to another messaging channel

Proposed Solution

Add image rendering support to webchat:

• Detect when read tool returns an image
• Display inline with proper MIME type
• Support message tool image attachments

Environment

• OpenClaw version: latest
• Channel: webchat
• Platform: WSL2 (Linux)
