Robert, This is an example of changing mapfile parameters via the request URL. It is documented on this page: http://mapserver.org/cgi/controls.html
If Steve's example using 'mapsize' doesn't work, I would try 'map_size'. You are just setting/changing the values for the SIZE and EXTENT properties in the MapFile. See the documentation here: http://mapserver.org/mapfile/map.html Also, I haven't tested it, but you could try specifying the map extent, which it sounds like you want to set to the same extent (bbox) as your image. I would try something like &map_extent=-97+43+-92+49 where the coords in the snippet match the bbox of your image. Note, you will want to make sure that the aspect ratio of your map_size matches the aspect ratio of your extent. If not, MapServer will adjust the extent to fill the image.

Ok after some sleuthing, I'm going to assume the bounding box of the image is that specified in the map file. Is there a way to specify it in the call? Also so more immediate questions: What kind of request is this? Is there a spec available? I'm really only used to GetMap requests so this is a little new to me.
