[Plugin: NextGEN Gallery] Show thumbnails on image browser

Hello,
I’ve tried to find some way to show the thumbnails when I’m in images browser, and so if I click the thumb~ it’s open on the same page in the images browser, is this possible?

Thanks.

Btw here’s a picture to show how I want it to work, sins my English isn’t the best. :p
