Have you read the docs? You should change the "image.tga" into the name of
the image you want to use as a heightmap for the heightfield. It looks like
you don't know this, but TGA is just a shortcut for Targa. It's a file
format for images with up to 24 bits of colors (16777216 colors). That's
one of the many image formats POV-Ray can read. Just chearching to TGA as a
keyword won't give you results.
For a newbie, it might be useful to first read the entire docs. If you
don't understand a part, just skip it until you need it. (At least that's
how I've learned to use the POVRay description language.)
Hope this helps
