Batch Generation

Tips for Better Results

1. Be specific - More detail = better results
2. Include style keywords - "4k", "cinematic", "digital art", "photorealistic"
3. Specify lighting - "dramatic shadows", "rim lighting", "candlelit"
4. Mention perspective - "from below", "bird's eye view", "close-up"
5. Use quality=hd for hero images and important assets

Troubleshooting

"Invalid API key" - Check echo $OPENAI_API_KEY is set

"Content policy violation" - Rephrase prompt to avoid flagged content

Image looks wrong - DALL-E interprets prompts creatively; try multiple generations or refine prompt
