There is currently no difference between the trial and purchased
version of
Shape2Earth when it comes to image capture. The accuracy is limted to
keep
within the Google Earth terms of use. I will go double check to make
sure
that the world file and real world coordinates are matching correctly.
Shape2Earth does not reproject imagery to get your data into UTM, but
you
can try some of the tools in MapWindow, or some of the GDAL tools :
