A jQuery plugin for file uploading using ajax(a sync); includes support for queues, progress tracking and drag and drop. Very configurable and easy to adapt to any Frontend design, and very easy to work along side any backend logic. The focus will be modern browsers, but also providing a method to know when the plugin is not supported. The idea is to keep it simple and lightweight. Basic Javascript knowledge is necessary to setup this plugin: how to set settings, callback events, etc. Initialize the plugin on any HTML element such as: <div /> to provide a Drag and drop area. All <input type="file"/> inside the main area element will be bound too. Optionally you can bind it directly to the <input />. Files will start uploading right after they are added. If using the queue system this option means the queue will start automatically after the first file is added.
