Displaying a jpg or icon image, this doesn't work.

I am trying to get this to work but it won't

  $Image = [system.drawing.image]::fromfile('c:\users\Public\Public Pictures\Sample Pictures\Desert.jpg')

  $form = new system.windows.forms.form
  $form.BackgroundImage = $image;$form.text = $Filename

  $size = $Image.size;$size.width += 8;$size.Height += 30
  $form.size = $size

  $form.topmost = $true
  $Form.Add_Shown({$form.topmost = $false})
  $form.showdialog()

Here is the error:

Exception calling "FromFile" with "1" argument(s): "c:\users\Public\Public Pict
ures\Sample Pictures\Desert.jpg"
