Image Alt Text

Most WordPress sites are missing alt text on over half their images, every one a keyword Google can’t read and a barrier for screen reader users. Image Alt Text fixes this directly from your WordPress dashboard. View every image with or without alt text, edit inline, copy filenames or titles in bulk, and keep your media library fully optimised without touching individual media files.

Whether you have 50 images or 50,000, Image Alt Text gives you a clear table view of your entire media library, shows exactly which images are missing alt text, and lets you fix them all in bulk, with no page refresh and no clicking through individual media items.

Image Alt Text Pro adds AI-powered alt text generation using OpenAI, Google Gemini, Claude AI, and Hugging Face, automatically on every upload, or across your entire library in one click.

Features

1. Alt text coverage dashboard: see at a glance what percentage of your images have alt text, with a colour-coded progress bar and with / missing / total counts at the top of every tab.

2. View all images with alt text: full table view with inline editing. No page refresh needed.

3. See every image missing alt text: dedicated tab showing only images that need attention.

4. Smart copy filename to alt text: one-click option to turn the image filename into clean, readable alt text. Automatically removes WordPress size suffixes (e.g. -1024×768, -scaled) and converts hyphens and underscores into words, in bulk or per image.

5. Smart copy post title to alt text: populate alt text from the associated post or page title, with separators and capitalisation tidied automatically (intentional brand casing like “iPhone” is preserved).

6. Bulk actions: select multiple images and apply alt text updates across all of them at once.

7. Search and sort: find any image instantly using table column search and sorting.

8. Multisite compatible: works across WordPress multisite networks.

9. Translation ready: every interface string (including the JavaScript messages and table UI) is translatable, with bundled German, Spanish, and Portuguese translations and a fresh translation template for the community.

Buy Pro Image Alt Text

1. 4 AI Vision Providers: Bring Your Own Key
   Generate highly accurate, SEO-friendly alt text using OpenAI GPT-4o, Google Gemini 2.0 Flash, Claude AI (Haiku), or Hugging Face (Qwen2.5-VL). Connect any provider with your own API key. Write a custom prompt tailored to your site’s tone and SEO goals. You pay the AI provider directly, with no markups and no bundles.

2. Auto-Generate Alt Text on Every Upload
   Set it and forget it. The moment an image is uploaded, alt text is generated automatically using your preferred method (OpenAI, Gemini, Claude, Hugging Face, Post Title, or Filename). No manual steps required.

3. One-Shot Bulk Actions
   Process every image in your current view with a single click. No selection needed, just pick an action (Copy Title, Copy Filename, or any AI provider) and click Process. Configurable batch size controls how many images are sent to the AI API per request.

4. Unlimited Bulk AI Selection
   Select any number of images in Bulk Action and run AI generation across all of them. Images are processed one at a time sequentially, with no timeouts or rate-limit errors regardless of selection size.

5. Send Image Context to AI
   Pass the image filename and the title of the post it is attached to into the AI request, so the alt text reflects real page context (ideal when the post title holds the venue, product, or location). Context usage strength (Strict, Balanced, or SEO) controls how strongly those keywords are used, and an optional Guarantee Keywords setting appends them when the AI leaves them out. Off by default.

6. AI Output Consistency Control
   Tune how consistent or varied the AI output is across runs, applied to every provider. Lower settings give steady, repeatable alt text; higher settings add variety.

7. Alt Text Prefix / Postfix
   Wrap generated alt text with fixed text such as a brand name or product type, with independent toggles for Copy Title, Copy Filename, AI generation, and Auto-Add on Upload. Leave the fields empty to change nothing.

8. Bulk Caption Actions
   Copy post titles or filenames to image captions in bulk. Also supports per-image caption update directly from the image list.

9. Decorative Image Accessibility (WCAG 2.1)
   Mark any image as decorative in the media library. The plugin automatically injects role="presentation" and aria-hidden="true" on the frontend so screen readers skip the image entirely. Covers both Gutenberg image blocks and PHP-rendered images.

10. SEO Quality Score for Every Image
    Every image in your library is rated Excellent, Good, or Needs Work based on alt text quality, so you can prioritise which images need attention first.

11. Visually Spot Missing Alt Text on Your Live Site
    Enable a frontend highlight to outline images missing alt text directly on your published pages. Instantly see where the gaps are without digging through the media library.

12. Advanced Date Range Filters
    Filter your image list by Today, Last 7 Days, Last 30 Days, Last 6 Months, Last 12 Months, Last 3 Years, or a custom range, ideal for large media libraries or audits.

13. Central Settings Panel
    Sidebar-navigated settings page to configure AI providers, API keys, custom prompts, upload automation, batch size, and highlight preferences, all in one place.
