DalleImageNodes - OpenAI DALL·E Nodes for ComfyUI

Overview

DalleImageNodes is a custom extension for ComfyUI that integrates OpenAI's DALL·E 3 API for:

• Inpainting (image editing)
• Image variation

This project supports the latest OpenAI Python SDK (v1.x) and automatically handles image resizing and format requirements (RGBA, fixed sizes) based on the examples from the offical Dall-E website.
