A note of security: Don't ever trust $_FILES["image"]["type"]. It takes whatever is sent from the browser, so don't trust this for the image type.  I recommend using finfo_open (http://www.php.net/manual/en/function.finfo-open.php) to verify the MIME type of a file. It will parse the MAGIC in the file and return it's type...this can be trusted (you can also use the "file" program on Unix, but I would refrain from ever making a System call with your PHP code...that's just asking for problems).
