The tga file contains ho height data because it has only one color - black.
With HF's you need to understand how they work when you are designing the
image to make terrain with it. Black = no height and white = maximum height.
For example if you go into a paint program and put white lettering on a
black background then render it the white lettering will become a raised
text object. If you put black lettering on a white background you will
end up with a raised background when you render it with the letters sunken
into the surface.
There is a great discussion on height fields at this site that you should
read for detailed info on the subject:

ok, that tga you posted is fine - however being totally black it will only
create a perfect flat plane.
open it up in psp, put some big white splodges on it, then try again.
black = 0 height
white = max height
