Single File Upload with Progress Tracking and a Sprite-skinned Button

This example demonstrates how to use the YUI 3 Uploader to send a single file to the server and to monitor the upload progress. The example also shows how to use a custom image skin for the "Browse" button used by the Uploader.

Please note: This example will not work when run from a local filesystem because Flash only allows ExternalInterface communication with pages loaded from the network. If you’d like to run this example locally, set up a local web server and launch it from there.
