AI captions/alt-text + SEO schema (Pro)​

This Pro plugin auto-generates alt text and captions using a provider-agnostic AI interface and emits Schema.org ImageObject for SEO.

Install and enable​

  1. Acquire a Pro license key (install from private npm if applicable)
  2. Configure the plugin with your provider adapter
  3. Pass your license key at runtime or via env

Runtime usage​

import { createAiSeoPlugin } from 'photoswipe-pro/src/pro/ai-seo.js';
import { MockCaptionProvider } from 'photoswipe-pro/src/pro/providers/mock.js'; // mock for testing

const aiSeo = createAiSeoPlugin({
  enabled: true,
  captionProvider: MockCaptionProvider,
  licenseKey: 'pswp_example_key_1234',
});

// Use with your PhotoSwipe Lightbox init

Provider interface​

  • generate({ url, title, hints }) -> { alt, caption, keywords }
  • Implement adapters for your chosen AI vendor(s)

Schema emission​

  • Emits an ImageObject <script type="application/ld+json"> per opened slide
  • For server-rendered schemas, disable client emission and render statically
