Dropbox updated its software to allow automatic uploading of photos and videos when you plug in a camera or smartphone via USB or insert a memory card into a USB reader on a computer with Dropbox installed. Adam Engst explained the features in depth last month. Dropbox increases free accounts from 2 GB to as much as 5 GB as you upload photos and videos. Version 1.4 is automatically installed on your computer to enable this feature. follow link
Using Expose within Spaces
To drag a file into an application that's running in another one of your Spaces, use Expose while in Spaces overview mode. First, press F8 to go into Spaces overview mode, then press F9 to Expose all application windows. Hover over the application window you want and wait a moment or press the Space bar, and both that space and that application come to the foreground, ready for you to drop the file.
