Easily bulk update image alt text in WordPress using image titles or a CSV upload. Improve accessibility and SEO with just a few clicks.

== Description ==
Alt Text Updater helps WordPress admins easily update alt text for images in bulk, improving accessibility and SEO. The plugin provides two powerful options to automate the process:

1. **Update Alt Text Based on Image Title**: Automatically update the alt text of all images in your media library using their image titles.
2. **Upload CSV to Update Alt Text**: Upload a CSV file with image URLs and corresponding alt text, and the plugin will update the alt text accordingly.

This plugin is designed for large media libraries, offering a real-time progress bar to track the update process.

**Key Features:**

- Update based on image title or CSV upload.
- Optimized for large media libraries.
