会不会是多余的空格或是换行造成的呢？

functions.php的文件是：

<?

function EventLog($EventType,$EventName,$EventDescription,$CheckNum,$UserAccount,$UserIP)
{
global $db, $card_data_eventlog_table;

$sql = "insert into $card_data_eventlog_table(eventtype,eventname,eventdescription,checknum,useraccount,userip,addtime) values ('$EventType','$EventName','$EventDescription','$CheckNum','$UserAccount','$UserIP','ghjg')";
$db->query($sql);
$sql="select max(id) from $card_data_eventlog_table";
$db->query($sql);
return $EventLog=$db->f(id);
}

//////////////////////生成校号=============
function GetCheckStr()
{
global $sessionchecknum;
while(($authnum=rand()%10000)<1000);
return $sessionchecknum=$authnum;
}
function GetCheckImage($CheckStr)
{
/*
* Filename: authimg.php
* Author: hutuworm
* Date: 2003-04-28
* @Copyleft hutuworm.org
*/

//生成验证码图片
Header("Content-type: image/PNG");
srand((double)microtime()*1000000);
$im = imagecreate(58,28);
$black = ImageColorAllocate($im, 0,0,0);
$white = ImageColorAllocate($im, 255,255,255);
$gray = ImageColorAllocate($im, 200,200,200);
imagefill($im,68,30,$gray);
//将四位整数验证码绘入图片
imagestring($im, 5, 10, 8, $CheckStr, $black);

for($i=0;$i<50;$i++) //加入干扰象素
{
imagesetpixel($im, rand()%70 , rand()%30 , $black);
}

ImagePNG($im);
ImageDestroy($im);

}

?>

根据这个错误
error,Cannot modify header information - headers already sent by (output started at D:\webs\autowebs\ocen\admin\include\functions.php:2) in D:\webs\autowebs\ocen\usersave.php on line 15
肯定是在header("location:PageInfo.asp?InfoType=RegErr&InfoNum=$eventid");
前面有输出
不如把functions.php也贴出来看看

再者Header("Content-type: image/PNG");这个语句是放在一个自定义函数中，没有执行这个函数则说明Header("Content-type: image/PNG");并没有被执行，应该也不会影响到usersave.php之中的header()

那是不是要把Header("Content-type: image/PNG");这句改成：<meta http-equiv="Content-Type" content="iamge/PNG; charset=gb2312">放在图片输出文件的<head></head>之中呢？
