Your Account Status page tells you just about everything you need to know about your account.
To get there:

1. Click on your username at the top-right corner of your Photobucket page
2. Select Account Settings
3. Choose the Account tab

This is what the Account Settings page looks like. (see below) 
On this page you can view your account type, membership creation date, total files uploaded, bandwidth use (meter on free account), stats, and the option to delete your account.
