基本都是function ImageResize($srcFile,$toW,$toH,$toFile="")这个函数出错。。。
请教高手这个问题该怎么改啊。。。急死了

//$uploadfile为你想要生成的文件的全路径
$file_Name = date("Y-m-d-H-i-s",time()).$_FILES['file']['name'][0];
$uploadfile=$uploaddir.$file_Name;

//但你实际从临时目录复制到的真正路径却是$uploaddir.$filename[$i]
move_uploaded_file($tmpname[$i],$uploaddir.$filename[$i]);

如果$uploadfile 和 $uploaddir.$filename[$i] 不相等，就是有问题的．
ImageResize函数读取的是$uploadfile，但实际上你真正的文件是$uploaddir.$filename[$i],所以导到找不到文件．

哇。。。。太感谢了，一语惊醒梦中人啊。。。
