Check if an image is loaded after x attempt(s) of x ms each

imageloader.js

function ImageLoader(url, callback, attempt_count, attempt_interval) {

    var $this            = this,
        callback         = callback,
        src              = url,
        attempt          = 0,
        attempt_count    = attempt_count || 5,
        attempt_interval = attempt_interval || 500,
        loaded           = false,
        intervalInstance;

    var img = new Image();

    img.onload = function() {
        loaded = true;
    }

    img.src = src;

    var intervalInstance = setInterval(function() { 
        if(attempt_count < attempt) {
            ++attempt;
        }
        else {
            clearInterval(intervalInstance);
            callback(loaded, img);
        }
    }, attempt_interval);
}

How to use:

var myimage = new ImageLoader( "http://example.com/myimage.jpg",  function(loaded, img) {
        if(loaded) {
            console.log('Image loaded');
            console.log(img);
        }
        else {
            console.log('Image fail');
        }
    },
    6, // = number of attempts
    500 // = duration in ms of an attempt
);
