Creating a Field in order to add Icons to content's Title
You can do this by creating node.tpl file.

    &lt;?php print render($title_prefix); ?&gt;
      &lt;?php if (!$page): ?&gt;
     //"print image here"  
 &lt;h2&lt;?php print $title_attributes; ?&gt;&gt;&lt;a href="&lt;?php print $node_url; ?&gt;"&gt;&lt;?php print $title; ?&gt;&lt;/a&gt;&lt;/h2&gt;
      &lt;?php endif; ?&gt;
      &lt;?php print render($title_suffix); ?&gt;


You can get all the field value here and just print the image before the title.
