Code:
procedure ShowSplashScreen(p1:HWND;p2:AnsiString;p3,p4,p5,p6,p7:integer;p8:boolean;p9:Cardinal;p10:integer);
external 'ShowSplashScreen@files:isgsg.dll stdcall delayload';
ShowSplashScreen(WizardForm.Handle,ExpandConstant('{tmp}\splash.png'),500,3000,500,0,255,True,$FFFFFF,10);
Replace 3000 with how long you want the splash screen image to show.
Replace either 500 to control fade in / fade out speed.
