1、打开 /dede/swfupload.php 找到，大概在137行

echo "FILEID:".$_SESSION['fileid'];

$file_snames = explode('.', $Filename);
$file_filename = $file_snames[count($file_snames)-2];
$_SESSION['file_filename'][$_SESSION['fileid']] = $file_filename;

/************************
//删除指定ID的图片
*************************/

/************************
//生成注释
function GetThumbnail(){  }
*************************/
else if($dopost=='thumbalt')
{
    if( empty($id) )
    {
        header('HTTP/1.1 500 Internal Server Error');
        echo 'No ID';
        exit(0);
    }
    if (!is_array($_SESSION['file_filename']) || !isset($_SESSION['file_filename'][$id]))
    {
        header('HTTP/1.1 404 Not found');
        exit(0);
    }
    if($cfg_soft_lang=='utf-8') $file_filename = $_SESSION['file_filename'][$id];
    else $file_filename = iconv( 'UTF-8', 'gb2312//IGNORE' , $_SESSION['file_filename'][$id]);
    echo $file_filename;
    exit(0);
}

2、打开 /dede/album_add.php 找到

$imginfo =  !empty(${'picinfook'.$k}) ? ${'picinfook'.$k} : '';

$imginfo =  !empty(${'picinfook'.$k}) ? ${'picinfook'.$k} : $_SESSION['file_filename'][$k];

3、打开 /dede/album_edit.php 找到

$imginfo =  !empty(${'picinfook'.$k}) ? ${'picinfook'.$k} : '';

$imginfo =  !empty(${'picinfook'.$k}) ? ${'picinfook'.$k} : $_SESSION['file_filename'][$k];

4、打开 /dede/js/handlers.js 找到

newImgDiv.innerHTML += '<div style="margin-top:10px">注释：<input type="text" name="picinfo'+albImg+'" value="" style="width:'+iptwidth+'px;" /></div>';

newImgDiv.innerHTML += '<div style="margin-top:10px">注释：<input type="text" name="picinfo'+albImg+'" value="" style="width:'+iptwidth+'px;" id="picinput'+albImg+'" /><span id="picinfo'+albImg+'" style="display:none;"></span></div>';
var picinfo = document.getElementById('picinfo'+albImg);
var picinput = document.getElementById('picinput'+albImg);
var myajax = new DedeAjax(picinfo,false,false,"","","");
myajax.SendGet2('swfupload.php?dopost=thumbalt&id='+pid);
picinput.value = picinfo.innerHTML;
DedeXHTTP = null;
