<p>By default, all images in WordPress posts link to themselves.  When a user sees a link, they click on it, and the image shows up by itself for no apparent reason.  This has several drawbacks:</p>
<ul>
<li>This is bad for SEO because these links are dead ends.</li>
<li>User experience is diminished due to wasted clicks.</li>
<li>Potential for higher bounce rate since no easy method is provided to get back to the site except for the browser “Back” button.</li>
</ul>
<p>This plugin uses a standards compliant HTML DOM parser (http://sourceforge.net/projects/simplehtmldom/). It does not use regular expressions (regex) to accomplish link removal and therefore will not break your site pages or mess up your theme.</p>

New images inserted into posts will have no links by default.  Existing self-links on all images are removed before the post content is shown.
