Mac People: Please help with my icons!!!?

I have an imac os x and i cant remember how i made the icons on my desktop so big, now i want them small again. If you know, please include the steps to change them back. Thanks!!!
For Mac People: Please help with my icons!!!? try this:

• I go with the "control click" (pretty much the same function as right click on a pc) and choose "view options"
  
• Right click (Or control click) on your desktop and click "Show view options". Then the scroller at the top sets size.
  
  That should be it.
  
  
  Hope that helps!
  
• Sam, Xaeno, and Janet are all right. I don't know who gave Sam the thumbs down but he is right.
  
• go to the Apple on the top left [click]
  go to preferences [click]
  go to dock [click]
  slide the "Dock Size" to your liking
  slide the "Magnification" to you liking
  [click] top left corner (to clear preference screen)
  WHAA - LAHH IT`S DONE!
  PEACE!
  SEA~
  
• In the dock, click the system preferences icon. Inside there click display icon and adjust the screen resolution to higher numbers.
  
• The only way I know to change the size of the DOC bar, is to go to preferences click the doc icon and make the doc size small and reduce the maginfication towards min. You can choose doc placement @ the bottom, left, or right. Good luck
  
• "right" click on desktop or on a group of icons. Change the view options. There should be an icon size preference.
