Get the Size of a CSS Background Image Using JavaScript?

Question

Is it possible to use JavaScript to get the actual size (width and height in pixels) of a CSS referenced background image?

Answer 1

var actualImage = new Image();
actualImage.src = $('YOUR SELECTOR HERE').css('background-image').replace(/"/g,"").replace(/url\(|\)$/ig, "");

actualImage.onload = function() {
    width = this.width;
    height = this.height;
}
