Name: Image Alt & Filename Generator
Industries: SEO, Automation
Date: May 2025 - July 2025
/ Provided Services
Generative AI development
Prompt design and pipeline for accurate, context-aware image descriptions.
Automation
Batch processing so an entire media library can be scanned and updated without reviewing every file by hand.
SEO
Filename and alt-text conventions tuned for image-search visibility.
/ Challenge
Sites with thousands of product and blog images had inconsistent or missing alt text, hurting both accessibility and image-search visibility - but rewriting them by hand wasn't a realistic use of anyone's time.
/ Solution
We built a pipeline that reads each image alongside its surrounding page context, generates a descriptive alt tag and a clean, keyword-aware filename, then applies both in bulk - with a review step before anything goes live.
/ Tech Stack
Chosen deliberately for what this project actually needed, not a default stack applied to everything.
Python
Image processing and the generation pipeline.
OpenAI API
Vision-based description generation.
Node.js
Batch job orchestration and the review dashboard.
/ Client's Feedback
We manage image libraries for a dozen client sites and alt text was always the thing that fell through the cracks. Now it's a batch job we run before every content push instead of a task nobody had time for.
