The Technical Process Simplified:

1. Image Acquisition: Import images via HTTP request (from sources like Pexels.com)
2. Optimization: Automatically resize images for optimal processing
3. AI Processing: Send images to Gemini 1.5 Pro with custom prompts
4. Caption Generation: Receive AI-created captions optimized for your specific needs
5. Positioning & Overlay: Dynamically position text on images based on content length
6. Distribution: Output ready-to-use captioned images for immediate deployment

The workflow leverages n8n's intuitive interface and requires minimal setup with just a Google Gemini API key and access to Google Drive for demonstration purposes.
