## What it is
A native image preloading component for WeChat Mini Programs, provided as a copy-in WXML/JS module with a Taro branch variant. It exposes an ImgLoader class that loads images and reports src, width, and height via callbacks.

## Use cases
- preload images in a wechat mini program
- get image dimensions after loading in wxapp
- load multiple images with progress callbacks in mini program
- avoid image pop-in when rendering lists in wechat app
- preload images in a taro project

## When to choose
- you are building a native WeChat Mini Program or Taro app and need image preloading with size info
- you want a lightweight, dependency-free component proven in production apps like JD Shopping

## When to avoid
- you are not targeting WeChat Mini Programs or Taro
- you need advanced image processing such as resizing or caching beyond preloading
- you require an actively maintained project with a license file
