[Plugin: NextGEN Gallery] How do Change the enlargement style for widget?

Hi

I have basically asked this before but not had any answer so here goes again, fingers crossed someone look 🙂

Basically when you click on the thumbnail from the sidebar NextGen Gallery widget it shows an enlarged Flash slideshow controlled by << >>. The problem is that there isn’t an obvious way for the user to close this (you actually click the image but I need it to be an X). I have used NG before on other websites with other themes and the ‘style’ of this slideshow enlargement is different, how can I alter this to look say like:

I am desperate to get this completed as it the last thing on the website, and very frustrating.

Thanks in advance for any time , and help given.
