Image and Media Support

Overview

The WhatsApp channel via Baileys Web supports media handling with specific rules for sending, gateway processing, and agent replies.

Key Features

CLI Command Structure The documentation specifies: openclaw message send --media <path-or-url> [--message <caption>] for transmitting media with optional accompanying text.

Media Processing Pipeline The system handles various file types differently:

Images undergo resizing and recompression to JPEG format with a maximum dimension of 2048 pixels
Audio files are converted to voice notes with the ptt flag enabled
Documents preserve filenames and support larger file sizes
MP4 files can enable looped playback on mobile clients using the gifPlayback parameter

Size Constraints

Outbound limits vary by media category:

Images are capped at approximately 6 MB following recompression
Audio and video files max out at 16 MB
Documents can reach up to 100 MB
Media understanding operations have separate thresholds (10 MB for images, 20 MB for audio, 50 MB for video)

Inbound Processing

When messages arrive with attachments, the system downloads media to temporary storage and exposes templating variables for command processing. Audio transcription enables slash command functionality, while image and video descriptions preserve caption text for parsing.
