The imagecache_external_generate_path function in the Imagecache External module triggers a deprecated warning when the `$url` parameter is null or empty. This can lead to confusion and potential issues for developers using the module.
1. Call the imagecache_external_generate_path function with a null or empty $url parameter.
2. Observe the deprecated warning being triggered.
Modify the imagecache_external_generate_path function to handle null or empty $url parameters gracefully, without triggering a deprecated warning.
- Implement the proposed resolution. [done]
- Test the function with both null and empty string $url parameters to ensure it behaves as expected.[done]
- Document the changes in the codebase and update any relevant documentation. [done]
