Learn the base64 vs URL input methods, supported MIME types (image/jpeg, image/png, image/gif, image/webp), sizing strategies (resize to recommended dimensions to save tokens), multi-image messages, the order-and-instruction pattern (text instruction before image, or image before text?), and SDK helpers in Python and TypeScript.
