```untrusted-server-text
Uploads an image or video to Auto Poster media library. Accepts files generated in ChatGPT (e.g. DALL-E images in /mnt/data/), uploaded files, or public image URLs. Direct chat download limit is 100MB. For larger videos or files (>100MB), tell the user to provide a direct public file URL or use autoposter_get_media_upload_url for direct S3 upload up to 5GB.
