Schema Gallery is a lightweight, AI-friendly WordPress gallery plugin that automatically adds valid JSON-LD ImageObject schema markup for every image in your gallery.

Perfect for photographers, agencies, and businesses who want their visual content to be properly recognized by Google, Bing, and AI-powered search results.

Key Features (Free Version):

Schema Gallery block for the WordPress editor — pick a gallery, see a live preview.
Add images straight from your Media Library — titles and alt text come along as schema data.
“View Your Schema” panel — see the exact JSON-LD your gallery outputs and test it in Google Rich Results with one click.
One connected ImageGallery schema node per gallery — cleaner, richer markup than loose per-image blocks.
Captions toggle and 2/3/4 column layouts, per gallery.
A ready-made sample gallery on first install, so you can see completed schema from minute one.
Create unlimited galleries with unique shortcodes.
Upload multiple images at once with drag & drop, then add schema details to each image afterwards.
“Needs schema” status shows which images still need a description and keywords.
Automatic JSON-LD ImageObject schema markup for each image.
Schema fields include: name, description, keywords, author, license, datePublished, and more.
Built-in pagination (18 images per page).
Responsive grid and custom lightbox with next/previous navigation.
Fully compatible with major themes and browsers.
Removes Google’s optional schema warnings when an author is set.
Clean, lightweight code – no external library dependencies.

Optimized for AI Search:

Schema Gallery is built for the future of SEO — where AI systems look for structured, machine-readable metadata to reference your content. Each image is wrapped in a compliant JSON-LD block, making it easy for AI to understand, cite, and recommend.
