按以下五个步骤进行修改就行了。

 修改 include/arc.archives.class.php

1.查找“//解析模板，对内容里的变动进行赋值”字段，在这段话上面添加以下代码 ：
 

function ClickPicNext($ismake=1,$aid,&$body) 
  { 
  global $cfg_rewrite; 
  if($this->NowPage!=$this->TotalPage) 
  { 
  $lPage=$this->NowPage+1; 
  if($ismake=0) 
  { 
  $body=preg_replace("/<(img|IMG)(.*)(src|SRC)=[\"|'|   ]{0,}((.*)>)/isU","点击图片,进入下一页<br/><a   href='".$this->NameFirst."_".$lPage.".".$this->ShortName."'>"."\${0}"."</a>",$body); 
  } 
  else 
  {
//静态页
$PageList="<a href='".$this->NameFirst."_".$lPage.".".$this->ShortName."'>"."\${0}"."</a>";
//动态页
  //$PageList="<a href='view.php?aid=$aid&pageno=$lPage'>"."\${0}"."</a>"; 
  if($cfg_rewrite == 'Y') 
  { 
  $PageList = str_replace(".php?aid=","-",$PageList); 
  $PageList = preg_replace("/&pageno=(\d+)/i",'-\\1.html',$PageList); 
  } 
  $body=preg_replace("/<(img|IMG)(.*)(src|SRC)=[\"|'| ]{0,}((.*)>)/isU",$PageList,$body); 
  }
} 
  else 
  {
$body=preg_replace("/<(img|IMG)(.*)(src|SRC)=[\"|'| ]{0,}((.*)>)/isU",$this->GetPreNext('imgnext'),$body); 
  }

  return $body; 
  }

2.查找$this->Fields[$this->SplitPageField] = $this->SplitFields[$pageNo - 1]; 在其下面添加

if($ClickPicNext){ 
            $this->Fields[$this->SplitPageField]=$this->Fields[$this->SplitPageField]; 
            }else{ 
                $this->Fields[$this->SplitPageField]=$this->ClickPicNext($ismake,$this->Fields['id'],$this->Fields[$this->SplitPageField]); 
            }

3.查找$this->PreNext['next'] = "下一篇：<a href='$mlink'>{$nextRow['title']}</a> ";在其下面添加

$this->PreNext['imgnext'] ="<a href='$mlink'>"."\${0}"."</a>";

4.查找$this->PreNext['next'] = "下一篇：没有了 ";在其下面添加

$this->PreNext['imgnext'] ="\${0}";

5.查找

else if($gtype=='next')
{
$rs =  $this->PreNext['next'];
} 

在其下面添加

else if($gtype=='imgnext')                  
{  
$rs =  $this->PreNext['imgnext'];    
}
