Topic: Is this possible: get full screen version?

Can someone tell me if it's possible to get a full screen version of SimpleViewer?

What I want:

1. Have the mini version

2. have an extra button for the large version

3. When the extra button is clicked, the same thumbnails (or larger ones) load + bigger images load

I'm sure I've seen this functionality elsewhere...!
Not sure if it was SImpleViewer

Thanks
