## What it is
A simple jQuery plugin that adds Medium-style smooth image zooming to web pages. Images marked with a data-action attribute expand smoothly on click and dismiss via scroll, click, or the escape key.

## Use cases
- add medium-style image zoom to a blog
- make images clickable and zoomable with jquery
- smooth image lightbox for articles
- zoom images on click in a static site
- open full-size image from thumbnail with meta-click

## When to choose
- you already use jQuery and want a lightweight image zoom
- you want the exact Medium-style zoom interaction
- you need a minimal drop-in script with a data attribute API

## When to avoid
- your project does not use jQuery
- you need a full-featured lightbox with galleries and captions
- you want a framework-native (React/Vue) zoom component
