## Effective Prompt Strategies

### Structure

For best results, include these elements in your prompts:

1. **Subject**: What is the main focus?
2. **Style**: Photo, illustration, 3D render, etc.
3. **Setting**: Where is the subject located?
4. **Lighting**: How is the scene lit?
5. **Perspective**: What angle is the subject viewed from?
6. **Colors**: What is the color scheme?

### Examples of Strong Prompts

**Basic prompt:**
"A coffee cup on a table"

**Improved prompt:**
"A ceramic coffee cup with steam rising, placed on a rustic wooden table by a window with morning sunlight streaming in, photographed with shallow depth of field, warm color tones"

## 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`
