[Plugin: NextGEN Gallery] Description in images too long.

Hello i’m using NextGEN gallery 1.9.6 in my website:
http://www.elrincondeenric.com/?page_id=33

If you click on the image from the left at the bottom of the gallery ( the one with a girl drawn in it ) u’ll see that the description of the image ( even tho is in spanish ) is too long for it to be shown, instead the text color turns white and makes it almost imposible to read.

My question is, how can i change that? Is there a way to view each image in a separate tab with a full shown description and title? Or can atleast show the whole description under the image when you click on it?

Thanks for your help 🙂
