Photo browser application? Just click icon and view photos on a NAS?

[NeilF]

Thinking of getting an adroid tablet, but one of my requirements would be to be able to browse the thousands of family photos we have on our NAS (or Windows PC)?

Ideally, I'd like to just click an icon on the tablet which then opens up the application defaulting to my photo folder on the NAS (or Windows PC). That folder will have a whole massive tree structure of child folders and pictures that I'd just like to be able to navigate and view...

Possible?

Thanks...
