​
Integration with Other Nodes

The Generate Image node pairs effectively with:
  • Slack Message Sender: Share generated images directly in channels or DMs
  • Google Drive File Writer: Save images to your Drive for storage or sharing
  • Gmail Sender: Include generated images as email attachments
  • Content Management Nodes: Incorporate images into CMS posts via API

​
Important Considerations

  • Restricted Content: The model won’t generate inappropriate or harmful imagery. Refer to OpenAI’s docs for content guidelines.

​
Troubleshooting

If your images aren’t generating as expected:
  • Prompt Clarity: Be more specific about what you want to see
  • Style Guidance: Explicitly mention the artistic style or medium
  • Composition Details: Specify camera angle, lighting, and scene details
  • Technical Terms: Use photography or design terminology for more precise control
  • Iteration: Try variations of your prompt to find what works best using Loop Mode
