I would like to know how to hide the image once it is clicked and the text is shown.

I have been able to solve the question of hiding the image by modifying this line: 

 <h3><a  href="#"  id='loadingImage'><img src="images/services_chart_01.jpg"  onclick="document.getElementById('loadingImage').style.display='none';"></a></h3>

Now that the image is hidden and the collapsible content (text) is being shown and the bar show a (-) minus sign: How can I reinsert the image back when I close the content being shown by clinking on the (-) minus icon.
