## What it is
Galleria is a free, open-source JavaScript image gallery framework for creating responsive, touch-friendly photo galleries on the web. It ships with a core library plus multiple themes and supports pulling media from sources like Flickr, Vimeo, and YouTube.

## Use cases
- add a responsive image gallery to a website
- display photos with swipe gestures on mobile
- build a gallery from a Flickr set or YouTube videos
- create a custom gallery theme
- serve retina-quality images with srcset support

## When to choose
- you need a ready-made, themeable image gallery with minimal code
- your gallery must work well on touch devices and responsive layouts
- you want an MIT-licensed gallery with no restrictions

## When to avoid
- you need a modern framework-native component (React/Vue) rather than a jQuery-era library
- you require heavy image editing or processing, not just display
- you need active feature development - the project is mostly in maintenance

## Facets
- artifact type: library
- maturity: maintenance
- function: ui-components, image-processing, animation
- domain: web-development, frontend, media, photography
- platform: browser, cross-platform
- tags: image-gallery, responsive-design, touch-support, themes, javascript, nodejs
