PageMonitor Regex？

Question

如何在此处使用PageMonitor Regex扩展程序https://chrome.google.com/webstore/detail/page-monitor/ogeebjpdeabhncjpfhgdibjajcajepgg检查网页上图像的任何更改，或者网页上是否有新图像？

我相信我可以用正则表达式来做，但我不太确定

<img src="//a.thumbs.redditmedia.com/IfVRE-
Cq7BWXAly4GHbPJrTh5GjQgh6iC01RspCa8I0.jpg" width="70" height="52" alt="" 
class="hoverZoomLink">

假设我有那个代码，如果对“IfVRE- Cq7BWXAly4GHbPJrTh5GjQgh6iC01RspCa8I0.jpg”有任何更改，我希望pagemonitor通知我..我该怎么做？

应该很容易，拿这个刮刀旋转..

/<img(?=(?:[^>"']|"[^"]*"|'[^']*')*?\ssrc\s*=\s*(?:(['"])\s*\/\/a\.thumbs\.redditmedia\.com\/IfVRE-\s*((?:(?!\1)[\S\s])*?)\.jpg\s*\1))\s+(?:"[\S\s]*?"|'[\S\s]*?'|[^>]*?)+>/
