You have to customize WizardForm.InstallingPage:

• Hide the FilenameLabel and StatusLabel
• Add you custom label
• Add the image

For the first two:

procedure InitializeWizard();
var
  CustomStatusLabel: TNewStaticText;
begin
  WizardForm.FilenameLabel.Visible := False;
  WizardForm.StatusLabel.Visible := False;

  WizardForm.ProgressGauge.Top := WizardForm.InstallingPage.Height - ScaleY(60);

  CustomStatusLabel := TNewStaticText.Create(WizardForm);
  CustomStatusLabel.Parent := WizardForm.InstallingPage;
  CustomStatusLabel.Caption := 'Installing Colectica';
  CustomStatusLabel.Font.Size := CustomStatusLabel.Font.Size + 4;
  CustomStatusLabel.Font.Style := [fsBold];
  CustomStatusLabel.AutoSize := True;
  CustomStatusLabel.Top :=
    WizardForm.ProgressGauge.Top - CustomStatusLabel.Height - ScaleY(8);
  CustomStatusLabel.Left :=
    WizardForm.ProgressGauge.Left +
    ((WizardForm.ProgressGauge.Width - CustomStatusLabel.Width) div 2);
end;
