Google Drive trigger (scan for new files added in a specific folder)\n2. Download the added image file\n3. Analyse the content of the image and extract the file as Base64 code\n4. Merge Metadata and Base64 Code\n5. Code Node to write the Keywords into the Metadata (dc:subject)\n6. Convert to file and update the original file in the Google Drive folder\n\n## The following accesses are required for the workflow:\n- Google Drive: [Documentation](https://docs.n8n.io/integrations/builtin/credentials/google)\n- AI API access (e.g. via OpenAI, Anthropic, Google or Ollama)\n\nYou can contact me via LinkedIn, if you have any questions: https://www.linkedin.com/in/friedemann-schuetz"
