At the moment, changedetection.io only supports detecting changes in the Text of the webpage, however, you can also use the source: keyword in the URL to tell changedetection to return the HTML source.

So this means that you could use changedetection to detect when the HTML now references a different image source.

For example

The source at https://example.com is

<HTML>
<BODY>
   <div id="wrapper">
      <img src="november-calendar.jpg">
   </div>
   <div id="other stuff">
     our new calendar!
    </div>
</BODY>
</HTML>

By specifying source:https://example.com and a filter of #wrapper, you will get a notification when the website changes "november-calendar.jpg" to "december-calendar.jpg"
