Another option is to use VisAD's Jython connection to do these.  Here's a
sample script that will take a GIF image, assume that it is a rectangular
projection between longitudes -110:-70 and latitudes 33:53, recast it into a
new domain, and display it along with a basemap.  It does, however, extract the
number of rows and columns from the GIF file.

You will, of course, have to substitute your own files and coordinates, but I
only offer this as an example:  

from visad.python.JPythonMethods import * 
from visad import * 
clearplot()
a=load("../data/mcidas/goes.gif") 
xsize = a.getDomainSet().getX().getLength()
ysize = a.getDomainSet().getY().getLength()
dom=Linear2DSet(RealTupleType.SpatialEarth2DTuple,-110,-70,xsize, 53,33,ysize)
typ = MathType.stringToType("((Longitude,Latitude)->(red,green,blue))") 
ff = FlatField(typ,dom) 
ff.setSamples(a.getFloats())
plot(ff)
map=load("../data/mcidas/OUTLUSAM")
plot(map)
