Mosaika — Responsive Photo Galleries

Mosaika makes building a gallery feel like arranging photos on a board. Galleries are a custom post type, so you manage them like posts; the editor itself is a mosaic of your images — pick from the Media Library, drag tiles to reorder, remove with one click. Choose grid, masonry or justified rows, set columns, gap, captions and a lightbox, then embed anywhere with [mosaika id="N"] or the Mosaika Gallery block.

The lightbox is small, self-contained and accessible — keyboard navigation (ESC, ←/→), managed focus and captions, with no external JavaScript library. Frontend CSS and JS load only on pages that contain a gallery, and images lazy-load. Built to WordPress standards — capability checks, nonce-verified saves, sanitised input, escaped output — translation-ready, no build step. Mosaika never deletes your Media Library files.
