Adding user icons to the XP Home Edition
Windows XP allows users to have small icons associated with their username. These icons are located in:

C:\Documents and Settings\All Users\Application Data\Microsoft\User Account Pictures\Default Pictures

To add an image, it must be 48x48 pixels, 24-bit color, and in .BMP format. Place the new image in that directory and it will show up in the list of selectable icons.

謝謝，但是我是指登入畫面的底圖大小！
