[Plugin: NextGEN Gallery] Text panel

Hi, I have the NextGen plugin working on my local xampp machine ok. I have integrated to my header.php to display a slide show at the top of my page. I was however trying to get the effect that a lot of slideshows have with a pop up text panel from the bottom of my pictures with a description from the admin description field.

Anyone any ideas if this is possible, or does any additional plugin provide this functionality from the admin area.

I have spent a couple of days looking around the web for answers but drawn a blank.

Thanks in advance for any feedback
