上传图像到服务器+插入文件名到数据库

//This is the directory where images will be saved
$target = "/images/";
$target = $target . basename( $_FILES['photo']['name']);
//This gets all the other information from the form
$strListItemPic=(mysql_real_escape_string($_FILES['photo']['name']));
//Writes the photo to the server
if(move_uploaded_file($_FILES['photo']['tmp_name'], $target))
{
//Tells you if its all ok
echo "The file ". basename( $_FILES['uploadedfile']['name']). " 
      has been uploaded, and your information has been added to the directory";
}
else {
//Gives and error if its not
echo "Sorry, there was a problem uploading your file.";
}

    <input type="hidden" name="size" value="350000">
    <input type="file" name="photo">  

它爆发并得到"Sorry, there was a problem uploading your file.";

我稍后在MySQL语句中插入$strListItemPic，因此我可以在其他地方的变量中回显图片。

这段代码中有什么明显的错误吗?$target必须是绝对路径吗?
