Generate and quality control images with DALL-E 2 and human review loop

This n8n workflow automates the process of generating AI images using OpenAI's DALL-E 2 model with built-in human review and quality control. The workflow creates an image based on a predefined prompt, sends it for human review, and if the image is rejected, automatically generates a new version with an improved prompt. This is perfect for content creators, marketers, or anyone who needs high-quality AI-generated images with human oversight to ensure they meet specific standards.

Key Features: - Automated image generation using DALL-E 2 - Human-in-the-loop review process - Automatic regeneration if images are rejected - Customizable prompts and review criteria - Quality assurance workflow
