File Management

Naming Strategies

• timestamp: image_20250114_123456.png
• prompt: serene_japanese_garden.png
• custom: Your specified filename
• hash: img_a1b2c3d4.png

Organization Options

• none: All images in one directory
• date: Organized by date (2025-01-14/)
• aspect_ratio: Grouped by ratio (landscape/)
• quality: Separated by quality (hd/)

Advanced Features

Image Editing

Edit and enhance generated images:

// Generate base image
const baseImage = await client.callTool("generate-image", {
  prompt: "A mountain landscape",
  aspect_ratio: "landscape",
});

// Edit the image
const editedImage = await client.callTool("edit-image", {
  source_image: baseImage.data.file_path,
  edit_prompt: "Add dramatic storm clouds",
  edit_type: "background_change",
});

Batch Editing

Apply the same edit to multiple images:

const result = await client.callTool("batch-edit", {
  image_urls: ["image1.png", "image2.png", "image3.png"],
  edit_prompt: "Convert to black and white",
  edit_type: "style_transfer",
});

Tips for Success

1. Iterate Quickly: Start with standard quality for experimentation
2. Save Versions: Keep track of successful prompts
3. Combine Styles: Mix artistic references for unique results
4. Use Negatives: Specify what you don't want in the image
5. Test Variations: Try different aspect ratios for the same concept

Limitations

• Maximum prompt length: 4000 characters
• No explicit content generation
• Some artistic styles may be interpreted differently
• Generation time varies based on server load
