Hi, you can use a simple PHP script which will present a save as dialog to the user.
For an example check out download.php in Chameleon (chameleon.maptools.org).

I understand the mapscript for a WCS request, but I am still unsure how to download the data once it is returned from the server. You gave an example of a WCS GetCoverage Request as: $mapurl .= "request=GetCoverage&coverage=[layer_name]&crs=epsg:28992&resx=25&resy=25&format=image/tiff" So I am assuming that there is some php call that can be used to capture the returned image but I am not sure how to do this. Sorry to ask so many questions but there is just no good documentation out there for WCS.
