how to fit splashscreen on all screen

hi,

I use advsplash::show to show startimage before install.
How can I do the image on all screen?
Schall installer read resolution of user display
and for each resolution take the special bmp-file?

Thanks.

BgImage supports full screen images. To use advsplash anyway, you can check the resolution with the following script:
