Question

We need to show a loading image until the page large size of background image is loaded. This bg image will be called to body tag in the HTML file not through CSS.

Answer 1

Try this

$(document).ready(function(){
    //Display image here
}


$(window).load(function(){  
    //remove image
});  

So you display an image when the document is ready

And finally you remove the image when the page is loaded completly
