The Vault is a place to store files for easy retrieval from anywhere you can get an internet connection. Your files are kept private by the use of a screen name and password. To use the service you must register. All that is required is your name and email address. Your initial password will be sent to your email address. You can change it to whatever you wish after you log on.
In version 2.0, the current one, you may name, describe and group uploaded files (such as "personal favorites" or "Office" or "Boating", whatever you wish). You may display groups of pictures in a floating format. This is an experimental script, it will be changing soon.
