Note: This is a slightly better version of HOW TO: Use the Opus image viewer inside or outside of Opus.
The attached registry file will register Directory Opus as a program to open images in. You can then navigate to the "Default Programs" in Vista/Windows7 and associate the file types properly.
GPSoft, you may use this in the Directory Opus installer if you wish.
