<ul>
<li>Thumbnail</li>
<li>Medium</li>
<li>Large</li>
<li>Full</li>

When your permalink structure does not end by a trailing slash (/), all your links look like http://example.com/2009/05. Permalink Trailing Slash Fixer add the missing trailing slash.
<h4>Example</h4>
If you have a site with the following permalink structure <code>/%category%/%postname%.html</code> and your permalinks 
look like these:
<ol>
<li>Single Post: <code>http://example.com/my-category/sample-post.html</code>.</li>
<li>Category: <code>http://example.com/my-category</code>.</li>
<li>Archive: <code>http://example.com/2009/05</code>.</li>
<li>Page: <code>http://example.com/about</code>.</li>
</ol>
After activation of the plugin:
<ol>
<li>Single Post: not modified.</li>
<li>Category: <code>http://example.com/my-category/</code>.</li>
<li>Archive: <code>http://example.com/2009/05/</code>.</li>
