A freeware application for Windows called PicMe, scans your PC for your digital photos and then displays them in 3D stacks, like a digital shoe box. You can use PicMe to browse through your photos but you can also use the application to share them with your friends by using the integrated sharing feature. PicMe lets you share photos with friends on Flickr, Picassa, Facebook, or with other PicMe users. The free version lets you share up to 200 photos, but to share more, you'll have to pay. However, it's only $9.95/year for the next step up, which allows for 5000 photos. You can try PicMe by downloading the app from here.
