Experimental plugin. Back up your WordPress installation before activating or running any of this plugin's code. All responsibility for any issues, data loss, or damage rests solely with the person who installs and uses the plugin.

Manage alt text for every image in your media library from one place. Browse, filter, and edit alt text inline — individually or in bulk — without opening each attachment separately.

Requirements

WordPress 6.0 or later
PHP 7.4 or later
User role with the upload_files capability (Editor and above)

Installation

Copy or clone the alt-wizard-wp folder into your site's wp-content/plugins/ directory:

wp-content/plugins/alt-wizard-wp/
├── alt-wizard-wp.php
├── assets/
│   ├── css/admin.css
│   └── js/admin.js
└── includes/
    ├── class-alt-wizard-admin.php
    └── class-alt-wizard-ajax.php

In the WordPress admin go to Plugins and activate Alt Wizard For WordPress.
Navigate to Tools → Alt Wizard.

How it works

The image table

The main screen lists every image attachment in your media library. For each image you can see:

A thumbnail
The filename (links to the attachment edit screen)
Image dimensions
A status badge — Has alt or Missing alt
An editable alt text field
Save and Revert buttons

Editing a field and clicking Save writes the new alt text to the database via an AJAX request without reloading the page. Revert discards any unsaved changes and restores the field to the value it had when the page loaded.

Filters

Use the filter bar at the top to narrow down what you see:

Filter	Description
All images	Shows every image in the library
Missing alt	Shows only images with no alt text set
Has alt	Shows only images that already have alt text
Attached to a post/page only	Limits results to images embedded in content

You can also control how many images appear per page (80 / 200 / 500 / 1 000 / All). Click Apply filters to update the listing.

Bulk editing

Tick the checkboxes next to the images you want to edit, or use Select all on page to select every row at once.
Edit the alt text fields for your selected images.
Click Bulk Save Selected to save all changes in one go, or Bulk Revert Selected to discard them.

A status message above the table reports success or flags any rows that failed to save.

Permissions

The plugin checks the upload_files capability on every page load and every AJAX request. Users without this capability cannot view the page or save changes. Individual attachment edits are additionally gated by edit_post for the specific attachment, so authors cannot edit media uploaded by others.
