From browsers's and javascripts's point of view, the image is a closed entity. You can make however tricks with css to crop a portion of it: http://cssglobe.com/3-easy-and-fast-css-techniques-for-faux-image/[^].
In html5 you have some other tools too, like this: http://www.html5canvastutorials.com/tutorials/html5-canvas-image-crop/[^].

Hi friend,

Thanks for your reply but those links have code to display part of image "not to select part of a image", my problem is, I want to give some effects to perticuler part of a image.(original image should exist)

You didn't get the point: you can not select part of the image in javascript and apply some effect.
Can you give a link where we could see an example how did you imagined this?

I saw it in jquery plugin called imgareaselect http://odyniec.net/projects/imgareaselect/

,there he says, you can select a portion of image and plugin will assign a class name to that selected portion.

So tried animating selected portion using assigned class name but It did not work.

My code..

<html lang="en">
<head>
<link rel="stylesheet" type="text/css" href="css/imgareaselect-default.css" />
<script type="text/javascript" src="scripts/jquery.min.js"></script>
<script type="text/javascript" src="scripts/jquery.imgareaselect.pack.js"></script>
<script type="text/javascript" src="scripts/jquery.imgareaselect.js"></script>
<script type="text/javascript" src="scripts/jquery.imgareaselect.min.js"></script>
<script type="text/javascript">

$(document).ready(function () {
$('img#photo').imgAreaSelect(
{
handles: true,
onSelectEnd: function alertme()
{

$(".imgareaselect-selection").animate({
opacity: 0.25,
left: '+=50',
height: '200'
}, 5000, function() {
// Animation complete.
});
}
});//img area select end
});//documen t end
</script>
</head>
<body>
<div><img id="photo" src="watch.png"/></div>


</body>
</html>

That plugin allows you to visually mark a portion of the image.
