just use paint. 640x480 and save it as a 16-bit to the 'windows' folder.
I trying to make my own boot screen and I'm having some problems. All the sites I go that have been posted here are not really helpfull for the building of actual image. I have photoshop, I got the layers and all built I just can't get the progress bar to work or the actual image to show at the actual bootup window.
my image always ends up in the 900kb size, but I think that's slight too high.
