How It Works
The workflow begins by importing a list of photo URLs, typically from Google Drive. Each image is then downloaded and intelligently resized to ensure optimal processing by the AI. These prepared images are passed to a LangChain LLM node, which utilizes the Google Gemini vision model. This AI assesses the photo against detailed UK government passport photo rules embedded in its prompt. Finally, a structured output parser extracts the AI's analysis into a clear JSON format, indicating photo validity and specific reasons, ready for downstream applications or reporting.
