原文外掛簡介
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 — no page refresh, 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.

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 — no markups, no bundles.
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.
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.
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 — no timeouts, no rate-limit errors regardless of selection size.
Bulk Caption Actions
Copy post titles or filenames to image captions in bulk. Also supports per-image caption update directly from the image list.
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.
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.
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.
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.
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.
