Splash Screen & User/password Login Screen!

If anyone can help me on this I would be really grateful. I am creating a Theatre Booking Sytsme using Delphi 7 Personal Edition, and at current I have 3 forms. FrmMain, FrmSplash and FrmPassword. I need help on how to get a splash screen, which I want a timer event which will have a progress bar, and like every 2 seconds loads an image which I place on the form. Also, after the the splash screen has loaded, it will then move onto the password screen. Which will automatically load usernames into a LstBox from a text file or from the LstBox itself, and then there will be an Edit in which there will be a password inputted, and if the username and password match, it will them move on to the main form.Hope someone can help me.Thanks.
