You should be able to do that using the -a_srs option

Ok I tried the command and it seemed to work :) Thanks
By the way, if my image has no Coordinates system and my GCPs corresponds to
a certain projection/coordinate system, How I define now the coordinate
system in which that data is?
Thank you

Pixel and line in the description below are actually two different numbers, one
representing the pixel (x coordinate) and the line (y coordinate) of the point
in the image.
Hope this helps,

Hi,
Question on the -gcp option in gdal_translate. If i want to use it to specify
the geographic referencing of the four corners do i need to specify the center
of the pixel, or the UL of the pixel. (e.g. -gcp 0 0 34 115 OR -gcp 0.5 0.5 34
115 )
