Images live on the app server's local disk (uploads/), served through an authenticated, room-membership-gated endpoint since rooms can be private. Uploads are streamed with a byte-count cap, validated as genuine decodable images with Pillow (not just a spoofed Content-Type), and downscaled to 2000px on the longer side (except GIF, to preserve animation). Backend: MessageImage model + nullable Message.content/image_id with a content-or-image CheckConstraint, upload/serve endpoints in rooms.py, WS message envelope gains image_id, push notification body says "sent an image" for image-only messages. Frontend: Composer gets an attach button with upload progress and a thumbnail chip; MessageList renders images inline with a click-to-zoom ImageLightbox.
