🖼️ ImgGen Component: Progressive Streaming + On-Demand Download

Why

We want to create a React component <ImgGen /> to simplify working with callAI's imageGen function and provide a better user experience. The goals are:

• Progressive loading: Stream and display the generated images progressively if a URL is available (like in ChatGPT), for faster visual feedback.
• Conditional generation: Only trigger image generation if the onData callback is present, avoiding unnecessary API calls.
• Reactive updates: Automatically regenerate the image if prompt or options props change.
• Placeholder handling: Show a properly sized placeholder while the image is loading to prevent layout shifts.
• Data capture: Allow consuming apps to receive the raw ImageResponse via onData for caching or post-processing.

How

Usage Example

<ImgGen prompt="a cat peeling a banana" options={optionsObject} onData={handleData} />

Proposed Features

• Accept prompt (required), options (optional), and onData (optional).
• Do not trigger generation unless onData is provided.
• When triggered, call imageGen using prompt and options.
• If response includes url, show the progressive image via <img src="url" />.
• If response includes b64_json only, fallback to data:image/png;base64,....
• Use size option to determine placeholder dimensions.
• When the image is fully loaded, optionally allow download (future enhancement).
• Call onData with the full ImageResponse once available.
• Regenerate the image on prompt or options change (reactive design).
