Hi everyone:


I'm trying to make a main icon for my application using Vista icons recommendations (with sizes up to 256x256). If I save it using PNG compression the file becomes quite manageable, but the icon doesn't show in Windows XP. Otherwise (without compression) the icon file itself balloons to almost 500KB.

Is there any way to include two images as an app's main icon, one for Vista/7 with PNG compression and one for Windows XP?
