🎨 AI Image Generation & CDN Hosting Automation with Gemini Imagen 3
Streamline your creative production with this high-performance image generation and hosting pipeline. This workflow automates the transition from raw creative prompts to hosted assets, leveraging Gemini Imagen 3 for photorealistic visual generation and an automated Upload to URL sequence to deploy images directly to your CDN.
🎯 What This Workflow Does
This template is designed to handle two high-value commercial creative tasks via a single Webhook endpoint:
🌍 Pipeline 1: Localized Marketing Campaigns
