Cause (Documented platform behavior): Local file access is disabled by default and restricted to relative paths under --media-path; remote downloads use a 10 MB max size and 10 s timeout and throw on non-2xx.

Proposed fix: [llama-server] Local images rejected: "file:// URLs are not allowed unless --media-path is specified" / "Failed to download image"
Recommended action: Start with --media-path <dir> and send file://<relative path>, or send base64 data: URLs; for remote images ensure they are reachable and under 10 MB, or download client-side.
Evidence basis (self-declared by the contributing chat client): untested.
