打开 touch/forum/post.htm 模板，查找：

<input type="file" name="Filedata" id="filedata"

替换为：

<input type="file" name="Filedata" id="filedata" multiple="multiple"

查找：

$.buildfileupload({
	uploadurl:'misc.php?mod=swfupload&operation=upload&type=image&inajax=yes&infloat=yes&simple=2',
	files:this.files,
	uploadformdata:{uid:"$_G[uid]", hash:"<!--{eval echo md5(substr(md5($_G[config][security][authkey]), 8).$_G[uid])}-->"},
	uploadinputname:'Filedata',
	maxfilesize:"$swfconfig[max]",
	success:uploadsuccess,
	error:function() {
		popup.open('{lang uploadpicfailed}', 'alert');
	}
});

替换为：

for (var i=0;i<this.files.length;i++ ) {
    var file_data = [];
    file_data.push(this.files[i]);
    $.buildfileupload({
                    uploadurl:'misc.php?mod=swfupload&operation=upload&type=image&inajax=yes&infloat=yes&simple=2',
        files:file_data,
        uploadformdata:{uid:"$_G[uid]", hash:"<!--{eval echo md5(substr(md5($_G[config][security][authkey]), 8).$_G[uid])}-->"},
        uploadinputname:'Filedata',
        maxfilesize:"2000",
        success:uploadsuccess,
        error:function() {
            popup.open('上传失败，请稍后再试！', 'alert');
        }
     });
}

上传覆盖，更新缓存。
