I just tested it and it looks like comma separated does not work, but  
space or tab separated does.  Each line must contain the same number  
of columns as the first.  The text file should contain only the image  
data. Your height data will be preserved in whatever units they are  
currently in.

After you load the image, you can set the x-y scale using Image-
 >Properties... or Analyze->Set Scale...
