* [JavaScript Load Image library](https://github.com/blueimp/JavaScript-Load-Image) v. 1.13.0+: Required for the image previews and resizing functionality.
* [JavaScript Canvas to Blob polyfill](https://github.com/blueimp/JavaScript-Canvas-to-Blob) v. 2.1.1+:Required for the image previews and resizing functionality.

The user interface of all versions except the jQuery UI version is built with [Bootstrap](http://getbootstrap.com/) and icons from [Glyphicons](http://glyphicons.com/).
[Cross-domain File Uploads](https://github.com/blueimp/jQuery-File-Upload/wiki/Cross-domain-uploads) using the [Iframe Transport plugin](https://github.com/blueimp/jQuery-File-Upload/blob/master/js/jquery.iframe-transport.js) require a redirect back to the origin server to retrieve the upload results. The [example implementation](https://github.com/blueimp/jQuery-File-Upload/blob/master/js/main.js) makes use of [result.html](https://github.com/blueimp/jQuery-File-Upload/blob/master/cors/result.html) as a static redirect page for the origin server.
The repository also includes the [jQuery XDomainRequest Transport plugin](https://github.com/blueimp/jQuery-File-Upload/blob/master/js/cors/jquery.xdr-transport.js), which enables limited cross-domain AJAX requests in Microsoft Internet Explorer 8 and 9 (IE 10 supports cross-domain XHR requests).
The XDomainRequest object allows GET and POST requests only and doesn't support file uploads. It is used on the [Demo](https://blueimp.github.io/jQuery-File-Upload/) to delete uploaded files from the cross-domain demo file upload service.
You can add support for various backends by adhering to the specification [outlined here](https://github.com/blueimp/jQuery-File-Upload/wiki/JSON-Response).
