Save the image as a .bmp

After the file is created, double click to open the file. Save the image name with the extension .bmp - such as mylogo.bmp (only put the image name and extension in the file)
Save the image in the C://Program Files/Micro$ale/Picture Files directory
Save the dat file in the C://Program Files/Micro$ale/Dat Files directory (the Dale Files List is unused dats)
