Creo Image Generation

Creo Image Generation

Generate, optimize, and manage marketing images using AI (DALL-E 3 or ComfyUI with Stable Diffusion XL).

Commands

| Command | Description | |---------|-------------| | /creo image-generation generate | Generate all images using DALL-E 3 | | /creo image-generation generate --seo-only | Generate only SEO/OG images | | /creo image-generation generate --optimize-only | Optimize existing images (resize, compress) | | /creo image-generation estimate | Show cost estimation without generating | | /creo image-generation optimize | Optimize all images in output directory | | /creo image-generation comfyui | Generate images using local ComfyUI (SDXL) | | /creo image-generation comfyui landing | Generate only landing page images via ComfyUI |

How It Works

DALL-E 3 (Cloud)

1. Reads image configuration from paths.js (or uses defaults)
2. Loads prompts from a prompts.js file (set via PROMPTS_FILE env var)
3. Generates images via the OpenAI DALL-E 3 API
4. Skips images that already exist on disk
5. Optionally generates SEO overlay images
6. Optimizes all images (resize, compress with sharp)

ComfyUI (Local)

1. Requires a running ComfyUI instance (see comfyui/SETUP.md)
2. Sends workflows to ComfyUI via its REST/WebSocket API
3. Uses Stable Diffusion XL models for photorealistic output
4. Supports batch generation by category

Environment Variables

| Variable | Required | Description | |----------|----------|-------------| | OPENAI_API_KEY | Yes (DALL-E) | OpenAI API key for DALL-E 3 generation | | IMAGE_CONFIG_DIR | No | Directory containing paths.js config | | IMAGE_OUTPUT_DIR | No | Output directory for generated images | | PROMPTS_FILE | No | Path to prompts.js with generation prompts | | APP_NAME | No | Application name for SEO image overlays | | COMFYUI_URL | No | ComfyUI server URL (default: http://127.0.0.1:8000) |

Cost Reference (DALL-E 3)

| Quality | Size | Cost per Image | |---------|------|----------------| | Standard | 1024x1024 | $0.040 | | HD | 1792x1024 | $0.080 |

Always run --estimate first to review costs before generating.

Library Reference

The extension code lives in the lib/ directory:

• lib/ImageGenerator.js -- Main generator class. Handles DALL-E 3 API calls, SEO image generation, and optimization.
• lib/PathManager.js -- Manages image path generation from configuration. Supports dynamic config parsing.
• lib/ConfigParser.js -- Parses TypeScript image configuration files to extract categories and image types.
• lib/utils.js -- Utility functions: file existence checks, cost calculation, file stats, sleep.
• comfyui/generate-batch.js -- ComfyUI batch generator. Sends workflows via WebSocket, supports category filtering.

Usage Examples

Generate with cost estimate first

# Check cost
node index.js generate --estimate

# Generate all
OPENAI_API_KEY=sk-... node index.js generate

# Generate HD quality
OPENAI_API_KEY=sk-... node index.js generate --quality=hd

ComfyUI local generation

# Start ComfyUI first, then:
node comfyui/generate-batch.js
node comfyui/generate-batch.js landing
node comfyui/generate-batch.js features audio

Optimize existing images

node index.js generate --optimize-only
