Is there a script to add the preview of an image as its icon?

Is there a script to add the preview of an image as its icon. When I save a image out of my nikon software it does not embed the icon preview. I would like to find a script or app the could do it fast. please help.

My app iMagine can do that. It might be a bit expensive for just the single task that you are asking of it, but if you decided to go ahead I would be happy to write the script for you to do the job.
