Indexhibit Support

Hi
I chose the exhibit format slideshow and like to have a short text only on the last image (it’s a white image), no text on the other images. How could I do that?
I have following text in the exhibit dialogue box in the cms, but no text ist shown on the homepage. Could anyone help me?

1. <div id='p12' class='pic' style='display: none;'><font color='#939393';><letter-spacing='2px';>
2. <br/>
3. <a onclick='show_image(1); return false;'>
4. text:<br/>
5. text<br/>
6. <a onclick="show_image(14); return false;" href="#"> < </a><span id="num12">12/12</span><a onclick="show_image(1); return false;" href="#"> > </a>
7. <br/>
8. </div>
