[GRASSLIST:1233] registring maps - one step ahead

Dear Sir,
          I have performed the registration of a scanned map. I found that whatever be the Dimension(w x h) of the image (eg. 720 x 960 pixels, 1590 x 1976 pixels, 1608 x 1964 pixels etc), the image after georegistration comes to a fixed Dimension of 29 x 29 pixels. Though the image which I am getting is very small and is suffering "chess board effect"; yet I am getting a georeferenced image. Where is the problem ? Why am I getting a image with the Dimension reduced to 29 x 29 in the another location if the image is showing the correct lat - long value. How should I rectify my problem? Please Help.
Thanks always.
