这无法通过Typo脚本来解决，因为src属性在功能的CImage硬编码：
$theValue = '<img src="' . htmlspecialchars($GLOBALS['TSFE']->absRefPrefix .
t3lib_div::rawUrlEncodeFP($info[3])) . '" width="' . $info[0] . '" height="' . $info[1] . '"' .
$this->getBorderAttr(' border="' . intval($conf['border']) . '"') .
$params .
($altParam) . ' />';
我看到修改的src属性是通过用户功能的唯一途径。 tt_news为用户功能提供了一个钩子，允许自定义处理图像（请参阅class.tx_ttnews.php的第2150行）。
实施例：
插入以下的TypoScript：
includeLibs.user_ttnewsImageMarkerFunc = fileadmin/templates/php/user_ttnewsImageMarkerFunc.php
plugin.tt_news.imageMarkerFunc = user_ttnewsImageMarkerFunc->ttnewsImageMarkerFunc
鉴于文件user_ttnewsImageMarkerFunc.php包含：
<?php
class user_ttnewsImageMarkerFunc {
/**

*
* @param array $paramArray: $markerArray and $config of the current news item in an array

大部分代码是从class.tx_ttnews复制。 PHP。最重要的行如下（每两个函数）：
str_replace('src="', 'class="lazy" data-original="', $pObj->local_cObj->IMAGE($lConf['image.']))
然后你会获得下面的图片标签：
<img class="lazy" data-original="uploads/pics/myimage.jpg" width="110" height="70" border="0" alt="" />
