Displaying An Image In The Background Of A Folder In Windows XP

1. Open Notepad.
2. Type the following in it :
3. [ExtShellFolderViews]
   [{BE098140-A513-11D0-A3A4-00C04FD706EC}]
   Attributes=1
   IconArea_Image=D:\Images\Pattern.jpg
   IconArea_Text=0x00FFFFFF
4. Save the file as Desktop.ini in the folder whose background you want to change.
5. Refresh. You picture is being displayed in the background of the folder.

You can replace  D:\Images\Pattern.jpg with a desired image path. 0x00FFFFFF can be replaced with any other colour's hexadecimal value.
It's funny to find softwares that simply write this file and change the background and funnier is seeing people admiring these softwares... Enjoy.!
