Benny, if you are scanning the laser to make the image then it is effectively only at a given position for a very short time that means that you need a bright laser to be able to see the image.
If you want the beam to follow the tool path slowly (slower) then that is different.
If you just want to have a go then get a pair of steppers and a pair of mirrors. You could use belt drives to increase resolution, some quick calcs should tell you how much you need. You then need to just run the g-code, the problem is that the x,y coordinates in the g-code need to be modified because the angle will be arctan(a/b) where a is the distance in x from the point beneath the laser and b is the height of laser above the bed.
Words to that effect anyway.
You might be able to write a gcode converter program to do this.
It would be fun to make some nice patterns anyway using this technique but without the conversion you will get compression of the tool path in certain areas and stretching in others.
