BlackBox UA 2017 by razor

[Kitsune1982]

hi guys, i am playing with the black box 2017 script rinaldo posted, and i cannot for the life of me figure out how to make a full screen welcome page bitmap. i have tried resizing it in photoshop, and adjusting the parameters in main.iss. here is my code

ExtractTemporaryFile ('Background.bmp');
WizardForm.WizardBitmapImage.Cursor:=crHand;
WizardForm.WizardBitmapImage.OnClick:=@LogoLabelOn Click;
WizardForm.ClientWidth:=800;
WizardForm.ClientHeight:=600;
WizardForm.InnerNotebook.Show;
WizardForm.OuterNotebook.Show;
WizardForm.WizardBitmapImage.Stretch:=True;
WizardForm.WizardBitmapImage.Parent:=WizardForm;


am i doing this wrong? i also cant seem to figure out how to line up the buttons either :< can someone tell me what i need to do or post a code snippet on how to add a background.bmp to the extracttemporaryfile variable? thanks!!
