Depending on how big it is, you can either tile it with gdal2tiles[1] or
serve it with mapserver[2].

For the first one you install gdal with python bindings, run gdal2tiles on
the geotiff, use a script (http://paste.ubuntu.com/928312/) to fix some
names, and serve that with apache. JOSM or Potlatch can then use it as a
background layer.

For the second one you install gdal and mapserver and tell it to serve the
geotiff and then you can add it as a background layer with JOSM or Potlatch.

I had a look at your town and given that it's a very small town and the bing
imagery is actually quite good, I don't know that it's worth doing any sort
of import. If you wanted street names you could get them from CanVec[3]. Of
course collecting street names also gives you a chance to tag businesses,
amenities, etc.
