First, let’s put the image in the page, and give it a width and height to make it smaller.

HTML

<div class="zoom">
	<img src="blueDoor.jpg" width="400" height="265" />
</div>

We will show the big image in the magnifier glass as background image, and change background image position while user move the mouse. If the mouse move out of the small image, we fade out the magnifier glass, vice versa. There is an illustration to show how we calculation the positions.

Make equal height columns by jQuery
