For content creators, agencies, and SaaS developers who need automated AI image generation and editing with professional delivery workflows.

Overview

This template demonstrates intelligent workflow routing based on user input type, leveraging Google's Gemini 2.5 Flash image model for both generative and editing tasks. The workflow includes complete file handling, cloud storage integration, and professional email notification with shareable download links.

Architecture & Key Features

Intelligent Input Detection - Conditional logic automatically detects presence of uploaded image files - Routes requests to appropriate processing branch (text-only vs. image+text) - Single webhook endpoint serves both use cases without manual intervention

Dual Processing Modes - Text-to-Image Generation (Prompt Only): User submits natural language description and the system generates new images from scratch using Gemini 2.5 Flash - Image-to-Image Editing (Prompt + Image): User uploads reference image with text instructions for AI-powered editing while maintaining image context

Complete File Management Pipeline - Extracts and validates uploaded image data - Converts AI-generated base64 responses to binary files - Uploads to organized Google Drive folder structure - Generates public sharing links with reader permissions - Implements proper file naming conventions with timestamps
