This little app runs on your iPhone and PC. It allows you to transfer files to and cabfrom your PC. This app is incredibly handy for displaying graphic files. You can drop your files into folders or the main view. You can also create your own folders. The plus tab you see in the pic is for folder creation.
Next I will show you how to share with other people.
Step 1. Drop your files into the Public folder. See pic below:

Step 2. Check your DropBox app on your Windows Menu bar. It should have notified you that a file has uploaded. Go to the
Public folder and find your file . Click on the file with left mouse and this menu will appear:
Step 3. In the DropBox menu click on the Copy Public Link option. You will then get your link. The example file is test.jpg. Your link will look something like this:
http://dl.dropbox.com/u/3447837/test.jpg
Why is DropBox useful ? You can send pics to people using the DropBox URL and people will able to see it even when your computer is off. The DropBox URL works in most fgrums where photo uploading is allowed.
DropBox is free.
