Here's a simple example of taking an existing image and making a 1/4 sized
thumbnail:

  export snapshot from img 1 to tPictData as PNG
  create image
  put it into tImg
  set the text of tImg to tPictData
  set the width of tImg to (the width of tImg/4)
  set the height of tImg to (the height of tImg/4)
  set the lockLoc of tImg to true
  set the imageData of tImg to the imageData of tImg

Hope this puts you on the right track...
