wordpress plugin wp_editor doesn’t post images

I’m trying to create a plugin with a visual editor and add media button that can POST and insert into the database all the HTML data. Here is my code:

<?php
if($_POST){
   print_r($_POST);
   global $wpdb;
   $table_name = $wpdb->prefix . "eventi_ecm"; 
   $name = $_POST['name'];
   $text = $_POST['content'];
   //$rows_affected = $wpdb->insert( $table_name, array( 'time' => current_time('mysql'), 'name' => $name, 'text' => $text ) );
 }
 $settings = array('textarea_name' => 'content','media_buttons' => true,'tinymce' => false);
?>
<div>
    <h2>New Event</h2>
    <form method="post" action="http://test.ble-group.com/wordpress/wp-admin/admin.php?page=eventi_new_page">
        <div id="poststuff">
            <input type="text" name="name"/>
            <?php wp_editor( '', 'content', $settings ); ?>
            </div>
        </div>
        <input type="hidden" name="action" value="update" />
        <p><input type="submit"/></p>
    </form>
</div>

But when I try to insert images, the HTML code about the image it’s stripped. 🙁
