This question has already been answered here. With the use of HTML5, you can check the height and width of the selected image file.

var _URL = window.URL || window.webkitURL;

$("#file").change(function(e) {

    var image, file;

    if ((file = this.files[0])) {

        image = new Image();

        image.onload = function() {

            alert("The image width is " +this.width + " and image height is " + this.height);
        };

        image.src = _URL.createObjectURL(file);

    }

});

Here's a fiddle from that page to test it: demo
