Do you use a free Dropbox account for storing and backing up your files? If so, get this: the company is currently offering up to 4.5GB of extra free space for anyone willing to help it test out the software’s new auto photo import feature. Your first photo import will land you 500MB of extra space, and every 500MB of photos and videos uploaded afterward will score you an additional 500MB. The new feature helps you automatically backup your photos every time you connect your memory card, phone, or camera to your computer, and can be download here.
pretty much just upload photos and it will expand to 4.5gb
edit: add me and we both win and get extra space!
