Why Images.Media.insertImage doesn't require WRITE_EXTERNAL_STORAGE permission
<p>I realize even I do not have </p>

<pre><code>&lt;uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /&gt;  
</code></pre>

<p>in my `AndroidManifest.xml</p>

<pre><code>String path = Images.Media.insertImage(((Activity)MainView.this.getContext()).getContentResolver(), screenCaptureBitmap, "Title", "Description");
</code></pre>

<p>still able to write image file to location <code>/mnt/sdcard/DCIM/Camera</code>. May I know why is it so?</p>
