AI Image Captioning and Overlay Workflow

Overview

This n8n workflow automates the process of generating descriptive captions for images and then visually applying those captions back onto the image itself. It leverages the power of multimodal Large Language Models (LLMs) like Google Gemini to understand image content and produce relevant text. The workflow also utilizes n8n's image manipulation nodes to resize images, calculate text positioning, and draw the generated caption directly onto the image, creating a visually enhanced output.

This workflow solves the problem of manually captioning images and then separately editing them. It streamlines content creation, enhances image metadata, and provides a foundation for automated image annotation, watermarking, or descriptive overlays.
