What is Custom Image Generator?
The Custom Image Generator is a specialized component for Openclaw Skills designed to provide a universal interface for visual content creation. It allows developers to bypass provider lock-in by supporting any third-party image generation service that adheres to the standard OpenAI API format, including DALL-E, Azure OpenAI, and various Stable Diffusion proxies.
By configuring simple environment variables, this skill empowers your AI coding agent to produce high-quality images, handle local file persistence, and manage API authentication seamlessly. It is an essential tool for developers building multi-modal applications that require dynamic visual outputs from specific or private API endpoints.
Custom Image Generator Use Cases
- Automating the creation of marketing visuals and social media assets using custom AI models.
- Generating design mockups and UI placeholders directly from a coding workspace.
- Batch processing image generation tasks for dataset creation or creative projects.
- Routing image requests through private or enterprise-grade Azure OpenAI endpoints for enhanced security within Openclaw Skills.
How Custom Image Generator Works
- The user configures the target provider's endpoint, API key, and model ID via environment variables.
- A descriptive text prompt is provided along with optional parameters like resolution and quality.
- The skill constructs an authenticated JSON payload and sends a POST request to the specified API URL.
- The script parses the response, which can be either a Base64-encoded string or a remote URL.
- If a URL is provided, the skill automatically downloads the image data.
- The resulting visual is processed and saved as a local PNG file in the current working directory.
Custom Image Generator Setup
To get started with this skill in your Openclaw Skills environment, configure your credentials and install the necessary dependencies:
# Configure your API provider details
export IMAGE_API_URL="https://your-api-provider.com/v1/images/generations"
export IMAGE_API_KEY="your-api-key-here"
export IMAGE_MODEL_ID="your-model-id"
# Install the Python image processing library
pip install "Pillow>=10.0.0"
