What is Feishu Image Sender?
The Feishu Image Sender is a technical utility that simplifies the process of sending visual content through the Feishu (Lark) messaging platform. By integrating this tool into your suite of Openclaw Skills, you can automate the delivery of system screenshots, data visualizations, or status updates directly to specific users. It handles the complex multi-step process of authentication, image uploading, and message dispatching using standard Python libraries, ensuring high compatibility and minimal overhead.

How Feishu Image Sender Works
- The script initiates a request to the Feishu OpenAPI to obtain a valid tenant_access_token.

- It sends a formatted image message to the user using the previously acquired image_key.
