What method will alert the browser that an image has changed?
<p>I break the image cache by simply appending a </p>

<pre><code>?time=current_time_stamp
</code></pre>

<p>to my image urls when making a request.</p>

<p>However, I only need to break the cache immediately after the user has updated their photo.</p>

<p>I could add a timestamp to every image request of the user photo, but this seems like over-kill.</p>

<p>Is there a way to tell the browser, the image has been updated, please refresh your cache.</p>

<p>Otherwise I would need to append a time stamp or similar to all dynamic images, to catch any changes in the image.</p>

<p>Thanks</p>
