//		Test file to handle image uploads (remove the image size check to upload non-images)
//
//		This file handles both Flash and HTML uploads
//
//		NOTE: This is obviously a PHP file, and thus you need PHP running for this to work
//		NOTE: Directories must have write permissions
//		NOTE: This code uses the GD library (to get image sizes), that sometimes is not pre-installed in a 
//				standard PHP build.
