Form trigger (image prompt and image size input)\n2. Generate the Image via OpenAI API.\n3. Return the image to the input form for download.\n\n## The following accesses are required for the workflow:\n- OpenAI API access: [Documentation](https://docs.n8n.io/integrations/builtin/credentials/openai/)\n\nYou can contact me via LinkedIn, if you have any questions: https://www.linkedin.com/in/friedemann-schuetz"
