Go to Systems Preferences > Desk top and screensaver > desk top tab > and proceed to select a picture / background. The changes will be instant. There is a setting to change the picture randomly every so many hours at the bottom of the screen but not one that changes the picture on start up.

Don't let other people access your Mac in admin mode - they might change something a lot more important than the Desktop picture.
However you can use Automator: create an Application in it, and select 'Set the Desktop Picture' from the Library. Choose the picture you want. Save the application, then go to System Preferences>Accounts>Login Items and select the Automator application you just created. This will then run at startup and set your chosen picture.
