## What it is
An Android library that provides WeChat-style full-screen image, video, and GIF preview with smooth zoom transitions from thumbnails to full screen and back. It supports nine-grid photo layouts, custom image loaders, custom preview activities/fragments, and drag-to-dismiss gestures.

## Use cases
- preview images full screen from a nine-grid gallery like WeChat Moments
- add tap-to-zoom photo viewer to a chat app
- implement swipeable image pager with drag-down-to-close animation
- preview GIFs and videos from a thumbnail list
- build a custom photo browser activity with custom image loading library

## When to choose
- building an Android app that needs WeChat-like image/video preview with transition animations
- you want a customizable media viewer supporting custom loaders, indicators, and fragments

## When to avoid
- you need an iOS or cross-platform image viewer
- you need a maintained library with recent updates and modern AndroidX-only support
- you only need simple static image display without zoom or transitions
