经过多次测试，问题终于解决了。原因是ie会把 jpg、jpeg翻译成image/pjpeg，png翻译成image/x-png 。而火狐则很标准：jpg、jpeg翻译成image/jpeg，png翻译成image/png。
为了避免这个问题，我在多个浏览器上做了测试，结果如下：

firefox image/jpeg image/bmp image/gif image/png

ie 6 image/pjpeg image/bmp image/gif image/x-png

ie 7 image/pjpeg image/bmp image/gif image/x-png

ie 8 image/pjpeg image/bmp image/gif image/x-png

附 PHP 的全局数组 $_FILES的内容：
* $_FILES["file"]["name"] – 被上传文件的名称
* $_FILES["file"]["type"] – 被上传文件的类型
* $_FILES["file"]["size"] – 被上传文件的大小，以字节计
* $_FILES["file"]["tmp_name"] – 存储在服务器的文件的临时副本的名称
* $_FILES["file"]["error"] – 由文件上传导致的错误代码
使用时form要添加 enctype规定了在提交表单时要使用哪种内容类型如：enctype=”multipart/form-data”。
兼容：

$typeMap = array ('image/gif' => 'gif', 'image/jpeg' => 'jpg', 'image/png' => 'png','image/pjpeg'=>'jpg');


没有conf文件结尾的，在Firefox下是这样的类型：
    [name] => httpd.conf
    [type] => application/octet-stream

而在IE下：

下面归纳了大部分上传图片的类型，而这种问题可以通过查询下面的返回类型来解决：
