Find Image height and width in jsp

Hello,

I need to find the width and height of an image in jsp.

my code is as follows:

.

<input type="File" size="40%" name="file" onchange="changeImage(this)">

var imgRe = /^.+\.(jpg|jpeg|gif|png)$/i;

function changeImage(fileField) {

var path = fileField.value;

if (path.search(imgRe) != -1) {

document.getElementById('newImg').src = 'file://' + path;

} else {

alert("JPG, PNG, and GIFs only!");

fileField.value = "";

}

}

How can i get the width and height of an image?

Thanks and regards
