/ Project Details

Name: Image Alt & Filename Generator

Industries: SEO, Automation

Date: May 2025 - July 2025

/ Provided Services

01

Generative AI development

Prompt design and pipeline for accurate, context-aware image descriptions.

02

Automation

Batch processing so an entire media library can be scanned and updated without reviewing every file by hand.

03

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.
