Clickable banner/ header image in Setup program

inno-setup, installation, nsis

Solution

To make the welcome page's left image clickable, you can use the following:

[Code]
procedure OnBannerClick(Sender: TObject);
var
  ErrorCode: Integer;
begin
  ShellExec('', 'http://www.stackoverflow.com', '', '', SW_SHOW, ewNoWait, 
    ErrorCode);
end;

procedure InitializeWizard;
begin
  WizardForm.WizardBitmapImage.Cursor := crHand;
  WizardForm.WizardBitmapImage.OnClick := @OnBannerClick;
end;

Problem

I need to make an Windows installer either with NSIS or InnoSetup. The customer wants an image to be displayed in the installer dialogues/ wizard pages and the image needs to be clickable, e.g. open a browser window when clicked. Is this possible? If yes, is it also possible to use animated gifs?
