What it does
The Images tab in the Web Accessibility Toolkit scans your website for images that are missing alt text. This includes images in posts, pages, and custom post types. It then displays a list of those images, along with a preview of each image, file name, which post/page it is attached to (if any) and a field to add the alt text.
Why alt tags matter
Images without meaningful alternative text are inaccessible to users relying on screen readers. The alt attribute provides a text-based description of the image’s content and purpose. Fixing missing alt tags is one of the most common and important accessibility tasks under WCAG guidelines.
How to add bulk image alt tags
- Go to Settings > Web Accessibility > Images from the WordPress admin menu.
- The plugin will automatically scan your site for images that are missing alt text.
- Each image will display:
- A small preview
- The file name and image ID
- The page or post it is attached to (if any)
- A text input to add an alt tag
- Save button
- You can manually type in the alt text for each image, or copy the image’s filename or the page/post title into the alt field using the provided buttons.
- There are also buttons at the top if the image table that allows you to bulk add the alt tags. Either by copying the filenames or the titles into the alt text field.
- Click the Save button next to each image to apply your changes, or simply hit the Save Changes button at the bottom of the page to save them all at once.
- The alt text will be saved directly to the WordPress media library and applied wherever that image is used.
Best practices for writing alt text
- Be specific and concise
- Describe the purpose of the image, not just its appearance
- Avoid phrases like “image of” or “picture of”
- Leave decorative images blank (alt=””) only if they truly add no meaning
Limitations
- Only images stored in the media library and inserted using WordPress functions are currently supported
- Background images or images added via third-party page builders may not appear here
