Change Resolution of JPEG?

[Sannyasin Sivakatirswami]

Is it possible to use or manipulate the imageData somehow to change the 
resolution of an image? Or, is importing a snap shot the only option to 
  get from a higher resolution to a lower resolution? I am not talking 
about JPEG Quality here, but going from a 200 DPI image to a 72 DPI 
version for the web or a thumbnail catalog.
