This is mainly for existing Dropbox users. Dropbox is testing out a new beta build and you could get an additional 5GB of space for free. All you need to do is install the experimental version of the client.
How it Works:
• 500MB of free space on first photo uploaded automatically
• 500MB of free space for each additional 500MB you upload (4.5GB max)
• Upload files of any size (no more 180 MB limit!)
• Files are limited to Pics/Videos i believe
I've only done this on a Windows PC/Android so i don't know how it works on a Mac/Linux.
Windows/Mac/Linux: (2/1) - Experimental Forum Build - 1.3.12 « Dropbox Forums
1. Install the experimental client
2. Put in an SD Card/USB/External Hard Drive with about 5-6GB of pictures/videos (I used JPGs and AVI files. Friend used mkv for videos and said it didn't work). When the Autoplay thing pops up click on "Import to Dropbox"
3. Let Dropbox import and it should create a "Camera Uploads" folder in your Dropbox and import your files. You don't have to wait for the 5GB worth of stuff to finish uploading just let it index so it recognizes that there is files that need to be uploaded
4. Delete the files you've imported (Or you can keep them if its actually stuff you want on dbox)
???
5. Profit

Theres also an Android APK where it'll automatically upload all the photos/pics you take from your phone to Dropbox directly and this will also apply to getting bonus space
