photo viewer with sub gallery?

view story

http://androidforums.com – I am very new to android (one day). I have looked around and fiddled a bit myself but cant find and cant do what I would like. I would like to put photos into folder within folders. ie I have a date folder and in that I want to put other folders with photos taken of different subjects on that date. I can create folders but every program Ive tried (ics gallery and quickpic) just seem to ignore any top level folder and just show all the sub folders. Im happy to pay for an app that will do this I just havent found one. Any clues? Thanks (General)
