In the fileupload.php file:

.The code is as follows:
Determine if it is a picture
Switch ($type) {
Case ' image/pjpeg ': $okType =true;
Break
Case ' image/jpeg ': $okType =true;
Break
Case ' image/gif ': $okType =true;
Break
Case ' image/png ': $okType =true;
Break
}

Above is to determine whether the file is a picture type, more file types, you can refer to the Tomcat/conf/web.xml file, the file type is very full ....
