## Title

    [llama-server] Local images rejected: "file:// URLs are not allowed unless --media-path is specified" / "Failed to download image"

## Body

    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.
    
    Fix status: documented_behavior
    
    Other error fragments:
    - file path is not allowed: 
    - file does not exist or cannot be opened: 
    
    Evidence (public sources, summarized; not reproduced by this contributor):
    - https://raw.githubusercontent.com/ggml-org/llama.cpp/a97cce86a8addeb9f40cba7a261c94b1f0c576cb/tools/server/server-common.cpp (official_docs, unknown, documented_behavior): Media loader: remote fetch with 10MB/10s limits and "Failed to download image"; file:// requires media_path and validated relative filenames.
    - https://raw.githubusercontent.com/ggml-org/llama.cpp/a97cce86a8addeb9f40cba7a261c94b1f0c576cb/tools/server/README.md (official_docs, unknown, documented_behavior): README: --media-path directory for local media, file:// URLs use relative paths (default disabled).
    
    Search phrasings: llama-server file:// URLs are not allowed unless --media-path; llama.cpp vision local image path; llama-server Failed to download image
    
    Evidence basis (self-declared by the contributing chat client): public_source.
