Review image alt text in the media library

Image Alt Text Pro is a WordPress add-on for reviewing and updating image alt text across a media library. Its coverage dashboard shows counts for images with alt text, images without it, and all images, alongside a colour-coded progress bar. A dedicated view focuses on images missing alt text. Search and sorting help locate specific entries, including WooCommerce product, gallery, and variation images. Inline edits update descriptions without a page refresh.

Choose a source for descriptions

Existing media information

Bulk actions can copy a cleaned filename or the attached post or page title into the alt text field. Filename cleanup removes WordPress size suffixes such as -1024×768 and -scaled, then turns hyphens and underscores into readable words. Title cleanup tidies separators and capitalization while preserving intentional casing such as “iPhone.” A fixed prefix or postfix can be added to copied, generated, or automatically added text.

AI vision providers

AI generation uses your own API key and supports OpenAI GPT-4o, Google Gemini 2.0 Flash, Claude AI with Haiku, and Hugging Face with Qwen2.5-VL. Choose a provider and generate descriptions in the WordPress dashboard. A custom prompt can guide their tone and SEO goals.

Generation is available for new uploads and existing images. Automatic generation can run on upload, and one-click bulk processing can work across the library. Process images in the current view without selecting them individually, set the batch size sent to the AI API, or choose any number of images for a bulk AI action.

Optional image context

The Send Image Context to AI option can include an image filename and its attached post or page title in the AI request. This gives the request context for terms such as a venue, product, or location. Choose Strict, Balanced, or SEO context strength to control how strongly those terms are used. The option is off by default.

Setup and compatibility

Install and activate Image Alt Text Pro in WordPress. If you want AI generation, connect a provider using your own API key. Open the media table to review coverage, then update images with inline edits, filename or title copying, or AI actions. For ongoing work, enable automatic generation on upload and use search, sorting, or bulk processing for the existing library.

The extension supports WordPress multisite networks and is translation ready, with bundled German, Spanish, and Portuguese translations. Technical questions and enhancement requests can be submitted through its native support forum.
