Image Generation

The image generation system creates pet and food images using Amazon Bedrock Titan Image Generator v2.

Prerequisites

  • AWS CLI v2 with Bedrock support
  • Bedrock model access enabled for Amazon Titan Image Generator G1 v2
  • jq installed

Usage

cd src/cdk/scripts

# Validate current status
./generate-images.sh --validate-only

# Generate all missing images
./generate-images.sh --create-zips

# Generate specific categories
./generate-images.sh --type kittens,petfood --create-zips

# Generate with different region
./generate-images.sh --region us-west-2 --create-zips

Image Categories

Category Count Naming Pattern
Bunnies 4 b1.jpg – b4.jpg
Kittens 7 k1.jpg – k7.jpg
Puppies 15 p1.jpg – p15.jpg
Pet Food 10 f1.jpg – f10.jpg

CDK Integration

Images are deployed via CDK:

  1. Generated images are zipped per category in static/images/
  2. CDK uploads them to S3 under petimages/ prefix
  3. CloudFront distribution serves images globally
  4. Applications construct URLs dynamically: ${IMAGES_CDN_URL}/${imageCode}.jpg

Model Access Setup

  1. Go to AWS Bedrock Console
  2. Enable access for Amazon Titan Image Generator G1 v2
  3. Wait for approval (typically instant)

Features

  • Exponential backoff retry logic for API rate limiting
  • Validation system for count, naming, and file integrity
  • Selective generation by category
  • Incremental updates (skips existing images)
