title: Inno Setup, change WizardImageFile during runtime
body: <p>Is it possible to change WizardImageFile during runtime? I want this picture to change on some condition. Couldn't change it in code, {code:GetGraphics} is also cannot be used in WizardImageFile parameter. 
  Has anyone changed it succesfully at runtime? Maybe there is another way to set WizardForm.WizardBitmapImage's picture?</p>
