An ico file is actually a collection of bitmap like images in various pixel and color formats combined in one file. On most systems two formats are very important:The 32x32 pixel format (this format is used for the desktop or the 'Large Icons' View in Windows Explorer or Macintosh, etc..) and the 16x16 pixel format (this format is used for your IE favorites, your taskbar, 'Small Icons' view in Windows Explorer, Macintosh, etc.). Each system will display an icon that fits best in the needed format, i.e. if your system can display 256-colored icons and you drop an icon on your desktop, your system will load the 32x32x256 icon. When your system can't find the icon format that is actually needed (i.e. Example #1 has no 16x16 pixel icon), the system will scale the 32x32x256 icon to 16x16 pixel format. (If your system can only display 16-colored icons, it will also reduce the color depth.) This may produce unexpected results. This is why we recommend you should make a 32x32, 256 color and a 16x16, 256 color version of your icon. Nearly all systems can display 256-colored icons, so there is no more need to make 16-colored icons.
