The BackgroundPicture setting assigns a background picture to the initial Keystroke startup screen (Logo Screen).
The picture file must be a Windows Picture file format such as .BMP, .PNG, .JPG, .GIF, or .TIF.
Use of the BackgroundPicture= setting without specifying a file name results in no picture being displayed at all.
A path and file name are required to define an alternate background picture file. Long file names are supported.
