bmp's or ico's for standard operations

Looking for a collection of bitmaps or Icons for standard items like
Open, Save, Print, Exit, etc.

I am accustomed to those provided by Lotus Ami Pro/Norton Desktop for
Windows and want to use similar looking buttons for my Toolbar.

Anything like those would be much appreciated or directions to find
them on the Net or Compuserve!

Many thanks,
