[tejasM17]

Feature Request: Add an image generator to the API using Ollama's Claude model.

Details:

• Integrate Ollama's Claude model into the backend.
• Implement an endpoint (e.g., /generate-image) that takes a prompt and returns a generated image.
• Ensure proper error handling and validation on input prompts.
• Return the generated image in a standard image format (e.g., PNG or JPEG).
• Add basic documentation for the new endpoint, including input/output formats and sample requests.

Acceptance Criteria:

• Endpoint for image generation exists, is functional, and uses the Claude model.
• Input prompts result in relevant image outputs.
• Clear documentation provided for new feature.

Notes:

• Consider rate limiting and security implications.
• Add tests for the new endpoint.
