<h1>Loading Images Below the Fold</h1>

|
<div class="exampleIntro">
|
|
<p>Often pages will have a number of images below the fold, hidden from the user's view. These are prime candidates to load with the <a href="http://developer.yahoo.com/yui/imageloader/">ImageLoader Utility</a>.</p>
|
|
|
|
<p>All the images in this example belong to the same group, and all load immediately only if they appear above the fold of the page.</p>
