For the below earth image

http://veimages.gsfc.nasa.gov/2430/land_ocean_ice_2048.jpg

how to assign the latitudes/longitudes to the corresponding
locations of the image? For example, if I plot a red point
on the location (lon,lat) then the corresponding location on
the image will show a red point.
