pkdsgn on "How showing description of parrent menu on menu-list, Image in menu"

Hello,
I'm trying show the description of parent menu in submenu.

I have something like that

<nav>
<ul nav-menu>
<li><a>item 1</a></li>
<li><a>item 2</a>
   <div class="dropdown">
   <span> $DESCRITPION_OF_ITEM_2</span>
   <ul sub-menu>
     <li>..</li>
     <li>..</li>
   <ul>
   </div>
</ul>
</nav>

I need showing this variable "$DESCRITPION_OF_ITEM_2" which showing the description from menu editor in wordpress, is it possible ?

And second question, do you know good plugins or something for adding image to menu ?

Thank;s for response
