jQuery: Check if image exists

Question

I\'m loading an image path via jQuery $.ajax and before showing the image I\'d like to check if it in fact exists. Can I use the image load/ready event or something similar

Answer 1

This is what I did of mine:

$.get( 'url/image', function(res){ 
    //Sometimes has a redirect to not found url
    //Or just detect first the content result and get the a keyword for 'indexof'
    if ( res.indexOf( 'DOCTYPE' ) !== -1 )  {
        //not exists
    } else {
        //exists
    }
});
