```html
<img src="img/blank.gif" alt="Photo" data-echo="img/photo.jpg">
```
## Demo
Check out a [demo of Echo](http://toddmotto.com/labs/echo).
## Installing with Bower
To install Echo into your project using Bower, use the GitHub repository hook:
```
bower install https://github.com/toddmotto/echo.git
```
## Manual installation
Drop your files into your required folders, make sure you're using the file(s) from the `dist` folder, which is the compiled production-ready code. Ensure you place the script before the closing `</body>` tag so the DOM tree is populated when the script runs.
```html
<body>
<!-- html content above -->
<script src="dist/echo.js"></script>

<script>
// call Echo.js
Echo.init();
</script>
