Code Examples

React/Next.js Integration

// components/GeneratedImage.tsx
interface GeneratedImageProps {
  prompt: string;
  width?: number;
  height?: number;
  model?: 'flux' | 'flux-realism' | 'flux-anime' | 'flux-3d' | 'turbo';
  className?: string;
  alt: string;
}

export function GeneratedImage({
  prompt,
  width = 1024,
  height = 1024,
  model = 'flux',
  className,
  alt,
}: GeneratedImageProps) {
  const encodedPrompt = encodeURIComponent(prompt);
  const url = `https://image.pollinations.ai/prompt/${encodedPrompt}?width=${width}&height=${height}&model=${model}&nologo=true`;

  return (
    <img
      src={url}
      alt={alt}
      width={width}
      height={height}
      className={className}
      loading="lazy"
    />
  );
}

// Usage
<GeneratedImage
  prompt="Modern tech startup office, glass walls, natural lighting, professional photography, 8k"
  width={1920}
  height={1080}
  alt="Hero background"
  className="w-full h-auto object-cover"
/>

With Next.js Image Optimization

// next.config.js
module.exports = {
  images: {
    remotePatterns: [
      {
        protocol: 'https',
        hostname: 'image.pollinations.ai',
      },
    ],
  },
};

// components/OptimizedGeneratedImage.tsx
import Image from 'next/image';

export function OptimizedGeneratedImage({ prompt, width, height, alt }) {
  const url = `https://image.pollinations.ai/prompt/${encodeURIComponent(prompt)}?width=${width}&height=${height}&model=flux&nologo=true`;

  return (
    <Image
      src={url}
      alt={alt}
      width={width}
      height={height}
      priority={false}
    />
  );
}

// Generate multiple images

Best Practices

DO

1. Use descriptive prompts - More detail = better results
2. Include quality modifiers - "8k, professional, detailed"
3. Specify the style - "photograph", "illustration", "3D render"
4. Define lighting - "studio lighting", "natural light", "cinematic"
5. Set appropriate dimensions - Match your actual use case
6. Use seeds for consistency - Same seed = reproducible results
7. Cache generated images - Save to CDN for production

DON'T

1. Don't use generic prompts - "a picture of something"
2. Don't request copyrighted content - No brand logos, celebrities
3. Don't use in loops without throttling - Rate limits apply
4. Don't skip the nologo=true param - Avoids watermarks
5. Don't generate same image repeatedly - Use seed + cache

Rate Limits & Caching Strategy

Pollinations Rate Limits

Production Caching Strategy

// Cache generated images to your CDN
async function getOrGenerateImage(prompt: string, options: ImageOptions) {
  const cacheKey = createHash('md5')
    .update(prompt + JSON.stringify(options))
    .digest('hex');

  // Check CDN cache first
  const cached = await cdn.get(`images/${cacheKey}.png`);
  if (cached) return cached.url;

  // Generate and cache
  const imageUrl = buildPollinationsUrl(prompt, options);
  const imageBuffer = await fetch(imageUrl).then(r => r.buffer());
  const cdnUrl = await cdn.upload(`images/${cacheKey}.png`, imageBuffer);

  return cdnUrl;
}

Troubleshooting

Integration with Frontend Design

When building websites/apps, this skill works seamlessly with frontend development:

1. During Development: Use Pollinations URLs directly as placeholders
2. Before Production: Generate final images and save to your CDN
3. For Dynamic Content: Use the API with proper caching

// Development: Direct URL (fast iteration)
<img src="https://image.pollinations.ai/prompt/..." />

// Production: Cached on your CDN
<img src="https://your-cdn.com/images/hero-cached.png" />

Activation Keywords

This skill activates automatically when you mention:

• "generate an image", "create a picture", "make an illustration"
• "hero image for", "banner for", "background for"
• "mockup of", "product shot", "app icon"
• "placeholder image", "avatar", "thumbnail"
• "illustration of", "graphic of", "visual for"
• Any image asset request during web/app development
