Switch -IIMG<name> - specify SFX logo
Specify a bitmap image file to display as logo in the created or updated SFX archive. The <name> parameter is a name of .bmp file including the full path. This switch is not supported in Windows 98 and Me. You must not compress SFX module by any third party executable compressors if you are going to use -iimg.
This switch is the command line equivalent of "Load SFX logo from the file" option in SFX options: Text and icon dialog.
Size of default SFX logo is 93x302 pixels. It is recommended to use bitmaps of same size or smaller.
