    while (attempts < maxAttempts) {
      try {
        const response = await openai.images.generate({
          model: 'gpt-image-1',
          prompt,
          n: 1,
          background: 'transparent',
          size: '1024x1024',
          output_format: 'png',

        const image = response.data[0].b64_json;
        return res.status(200).json({ photo: image });
        
      } catch (apiError) {
        attempts++;
        if (attempts >= maxAttempts) throw apiError;
        await new Promise(resolve => setTimeout(resolve, 1000 * attempts));
      }
    }
  } catch (error) {
    console.error('DALL-E API Error:', error);
    
    let errorMessage = "Something went wrong generating the image";
    let statusCode = 500;
    
    // Provide useful error messages based on error type
    if (error.status === 403) {
      statusCode = 403;
      errorMessage = "Access denied: API key permission issue";
    } else if (error.status === 400) {
      statusCode = 400;
      errorMessage = "Invalid prompt or parameters";
    }
    
    res.status(statusCode).json({ 
      message: errorMessage,
      error: {
        type: error.type || 'unknown_error',
        code: error.code || null
