smart-image-loader（智能图像加载器）

Smart Image Loader

Quick Start

When a user asks to display an image:

1. Check if input is a URL or local path

- URLs start with http:// or https:// - Local paths are file paths in the workspace

1. For URLs:

- Download the image to a temporary location using the Python script - Use read tool to display the image - Clean up the temporary file afterward

1. For local files:

- Verify the file exists (relative to workspace or absolute path) - Use read tool directly to display the image

Usage Examples

User says: "Show me this image: https://example.com/photo.jpg"

1. Run: python3 scripts/smart_image_loader.py https://example.com/photo.jpg
2. Script downloads to temp: /tmp/dir/photo.jpg
3. Use read tool on: /tmp/dir/photo.jpg
4. Clean up: Delete the temp file

User says: "Display ./images/logo.png"

1. Run: python3 scripts/smart_image_loader.py ./images/logo.png
2. Script verifies file exists
3. Use read tool on: /home/node/clawd/images/logo.png (absolute path)

Script Usage

python3 scripts/smart_image_loader.py <image_path_or_url>

Arguments

Output Format

The script returns a JSON-like output with:

• Status: SUCCESS or FAILED
• Type: url or local
• File Path: Local path for the read tool
• Message: Status description
• Cleanup Needed: true if temp file should be deleted
