Geo rectifing photos

[G. Zacharioudakis]

Hello Grassusers
We have some aerial photographs of an area.
We do not know the coordinates of each photo to put it 
in the location in GRASS but we know the coordinates of a few points 
which are easily identified on the photos.
How we can geo rectify the photos? (already converted to rasters) and 
put them in the correct order to produde the whole area of interest??

Thank you in advance for your help
