Upload ZIP of HTML Files

How to Use
Upload a ZIP archive containing HTML files. The tool extracts it into an isolated sandbox, scans every .html/.htm file with DOMDocument/DOMXPath for <img> tags with a missing or empty alt attribute, and fills each one in with a humanized version of the image's filename (extension and folder path stripped, dashes/underscores turned into spaces, and each word capitalized). You get a rebuilt ZIP with the fixes applied, plus a per-file report of how many images were updated. Review the generated alt text afterward β it's a solid starting point, not a substitute for a human description of genuinely meaningful images.
