Create an [ImgBB account](https://api.imgbb.com/) and get your API key\n2. Add your ImgBB API key to the HTTP Request node (key parameter)\n3. Optional: Configure OpenAI credentials for image generation\n4. Connect your image input source\n\n## How to Adjust it to Your Needs\n- Skip OpenAI nodes if using your own image files\n- Adjust image optimization parameters\n- Customize image hosting settings\n- Modify output format for your needs\n\n\nMade by Simon @ [automake.io](https://automake.io)"
