Re: Splash screen.

[Naba Kumar <kh_naba yahoo com>]

Thanks Steve. The idea of producing a splash screen
was great. But it uses xpm file for the image. As I
have already told the image is going to be anything
other than xpm. Can there be some way to display other
file formats (eg. jpg formate)in the given function?
