Exindium Alt Text Manager Documentation

The Overview gives you a quick snapshot of alt text coverage across your WordPress media library.

It shows:

• Total images in the current media library view
• Images that are missing alt text
• Current alt text coverage

Use the available actions to move directly to images that need attention. If media changes are not yet reflected in the statistics, click Refresh Statistics to clear the cached counts and sync the Overview with the current media library state.

Overview statistics are cached for 24 hours to reduce repeated database work.

Use the “Missing Alt Text” and “Alt Text Present” tabs to review and manage image alt text without opening individual media attachment pages.

This view shows images that currently have no alt text. Use it to find images that need attention and add alt text directly from the dashboard.

This view shows images that already have alt text assigned. Use it to review or update existing values.

Type or update the alt text in the image row, then save the change directly from the dashboard. You can also open the full-size image in a new browser tab when you need more visual context before writing alt text.

Use the Copy Filename action beside an image to generate a cleaned alt text value from its filename. This is useful as a starting point when the filename already describes the image.

Filename-generated text is a fallback or starting point. For meaningful images, descriptive alt text written for the image and its context is recommended

Select images and choose “Auto-fill from Filename” from the Bulk Actions menu to generate and save cleaned filename-based alt text for the selected images.

Manual selections are limited to the number of images currently displayed by your per-page setting. Select All selects all images displayed within that limit, and selections are cleared when you move to another page.

For larger automatic operations across all images that are currently missing alt text, use the dedicated Bulk Tools tab.

Bulk Tools can generate filename-based alt text for images that are currently missing it.

When a bulk process starts, Exindium Alt Text Manager queries the current number of images missing alt text directly rather than relying on the cached Overview statistics.

The operation processes images in batches and does not overwrite images that already have alt text.

A running bulk process can be paused and resumed. Progress is saved so the operation can continue after a page reload or interruption.

When a saved operation is resumed, the plugin reconciles it with the current media library state. Images that no longer need alt text are skipped rather than overwritten.

When processing reaches 100%, the completed state remains visible so you can confirm that the operation finished successfully. Leaving the tab or refreshing the page returns you to the normal Bulk Tools view.

Settings control how filename-based alt text is generated and whether it should be applied automatically to new uploads.

Existing alt text is preserved and is not replaced by this setting.

Enable this option to use the image filename as a fallback when a newly uploaded image does not already contain alt text.

• Keep Filename Formatting – keeps the stored filename formatting while removing the file extension and WordPress-generated final -scaled suffix.
• Clean Spaces & Caps – converts dots, underscores, and hyphens into spaces and capitalizes words.
• Clean & Strip Numbers – applies the cleaned formatting and removes standalone numeric values while preserving numbers that are part of words, such as PS5 or iPhone18.

Choose how filenames are formatted when they are used to generate alt text:

Exindium Alt Text Manager supports media libraries using WPML Media Translation and Polylang Media.

When a specific admin language is selected, the plugin follows that language context and displays the corresponding media entries and alt text. Changes to translated media versions remain independent according to the media translation structure provided by the multilingual plugin.

A multilingual plugin is not required to use Exindium Alt Text Manager. Language-specific media metadata requires the corresponding media translation functionality in your multilingual setup.

The Overview statistics also follow the selected language. When all languages are being viewed, the Overview displays the corresponding combined media library statistics.

By default, access to the Alt Text Manager admin area requires the WordPress manage_options capability, which normally restricts access to Administrators.

Developers can change the required capability using the exatm_minimum_capability filter.

Example:

Bulk Tools processes 25 images per batch by default. Developers can adjust the batch size using the exatm_bulk_batch_size filter. The minimum supported value is 1.
