ImagePreloader

Simple, fast and lightweight html-images preloader

$3

``javascript
var preloader = new ImagePreloader();

preloader.preload(urlOrImgElement1, urlOrImgElement2, urlOrImgElement3, ...)
.then(function(status){
console.log('all done!', status);
});
`
In this case, preload promise always will be fulfilled with the status of every image.

Or you can use a simple static method:
`javascript
ImagePreloader.simplePreload(urlOrImgElement)
.then(function(status){
console.log('all done!', status);
}).catch(function() {

});
`

In this case, preload promise will be fullfilled or rejected. It depends from image loading result.

This is a simple realization of HTML-image preloader that supports CommonJS, AMD and non-module definition.

There are a few cool features:
- promise-based flow
- progress callback support
- fallback image support
- working with either url or dom image element

Promise-based flow allows you to work with result of preloader as with simple promise(than it is in reality).

If onProgress-property will be settled to preloader instance, then preloader will be calling this callback after any image will be loaded(fail or success):
`javascript
var preloader = new ImagePreloader();

preloader.onProgress = function(info) {
console.log('image with source %s is loaded with status %s', info.value.src, info.status);
};

preloader.preload(urlOrImgElement1, urlOrImgElement2, urlOrImgElement3, ...)
.then(function(status){
console.log('all done!', status);
});
`

As well you can set fallback image, that will be replaced with if original image can not be loaded:
`javascript
var preloader = new ImagePreloader();

preloader.fallbackImage = fallbackImageUrlOrImgElement;

preloader.preload(urlOrImgElement1, urlOrImgElement2, urlOrImgElement3, ...)
.then(function(status){
console.log('all done!', status);
});
`
