Help needed in Raster/World file

[raffle peter]

   Hi
       I am trying to include a .tif file for raster background. For that i have to write a .tfw(world file) for the corresponding .tif file. The information that i need to put in the world file are X, Y Pixel size, rotational co-efficient and X, Y location of the center of the top left pixel. I am trying to find these values by using gdalinfo-- but some values are 0.0
  in their corresponding field.
     Can anyone plz help me, how to get/set these values for the world file so that i can
  keep my raster data georeferenced with other layers in my mapfile.
   
  Thanks in advance
