Use Case

I need to use OpenClaw browser Control UI (http://127.0.0.1:18789/) as my primary work interface because:

1. Large screen - much better for viewing documents, screenshots, and code
2. Multi-window - can reference materials while chatting
3. Already my daily workflow

Problem

Currently the browser Control UI does NOT support uploading images or documents. This forces me to use Feishu or WeChat for image/file sharing, which have smaller viewports and are less convenient for detailed work.

What I Need

• Upload screenshots directly in browser (drag & drop or file picker)
• Support common document formats (PDF, DOCX, TXT, code files)
• Support image formats (PNG, JPG, etc.)
• Large screen preview capability (which Feishu/WeChat cannot provide)

Why This Matters

This is a core workflow feature. The backend already supports media handling (per docs), but the UI layer is missing the upload component. There are already related issues (#56344, #36440) requesting similar functionality.

Suggested Solution

1. Add file upload button/area in the Control UI chat input area
2. Support drag & drop for files
3. Allow generic file types (not just images)
4. Show preview of uploaded files before sending
