what have you done so far? Can you post the code you are working so give a better idea how approach it.

you can take following function for getting size of image.

function getImgSize(imgSrc)
{
var newImg = new Image();
newImg.src = imgSrc;
var height = newImg.height;
var width = newImg.width;
alert ('The image size is '+width+'*'+height);
}

am trying to get image height and width by using following code but it's not working. and I get confused by some documents they are say like some property of local system files are available to access from java script like size but am unable to get those properties

var imgObj = document.getElementById('imageFile');
var newImg = new Image();
newImg.src = imgObj.attr('src');
var height = newImg.height;
var width = newImg.width;
