With current uDig, you'll have hard times, 25MB is a bit big for it, give it plenty of memory. And you have to write a .tfw file for it, see some docs here: http://www.omg.unb.ca/~jonnyb/processing/geotiff_tifw_format.html http://www.gdal.org/frmt_various.html#WLD In the future, with a uDig that uses geotools 2.3.x or trunk, it's going to be relatively quick, especially if you do use gdal_translate to pre tile it, and gdaladdo to add overviews to it. Pyramids, forget about them, the pyramid generator is broken at the moment, but besides this, you don't need a pyramid for such a "small" file (it's only 25MB).
