• Alt Text - Optional alternative text for the image.

How It Works

The Image node creates an image widget that displays an image from a URL. When executed, the node:

1. Validates the provided Session ID and Image URL
2. Retrieves the session information for the provided ID
3. Creates an image widget with the specified URL, label, description, and alt text
4. Sends the widget to the client with the specified session ID

Requirements

• A valid session ID for an active client connection
• Valid image URL
• Properly configured client interface that can display image widgets

Error Handling

The node will return specific errors in the following cases:

• Empty or invalid Session ID
• Session not found for the provided ID
• Image URL is required but not provided
• Image URL is empty
• Failed to send widget to client

Usage Notes

• The Session ID must match an active client connection
• The image widget is a visual element only and does not collect user input
• The Label and Description fields are optional but can help users understand what the image represents
• The Alt Text field is optional but provides accessibility benefits for users with screen readers
• Images should be hosted at publicly accessible URLs
