    ReprojectImage takes an image in some projection other than Equirectangular and produces an image in the Equirectangular projection. This step is usually the hard one. You would then take that image and run it through a piece of software such as Wilbur or Fractal Terrains (I'm most familiar with those two as I wrote them).
    In Wilbur you would reproject the Equirectangular image as follows:
    1. Load the image using File>>Open with the Type set to Color Image Texture.
    2. Set the map boundaries using Surface>>Map Info (Top=90, Left=-180, Right=180 and bottom=-90 for a whole-world image).
    3. Reproject the map using Window>>Map Projection. Pick the desired projection (Lambert Azimuthal Equal-area in this case) from the drop list and drag the image in the window around to get the desired result. For world endcaps you will want a Center of Projection with Latitude=90 for the north pole and Latitude=-90 for the south pole.
    4. Click Export BMP on the Map Projection window to save a bitmap of the desired resolution.

    Below are examples of this process on a basic Earth map to get polar caps.

    Cool, looks like it's exactly what I need!
    But I can't install Wilbur on my office PC, as the installer requires administrator privileges?!?
    Isn't any ZIP/portable version available?

    edit:
    ...and I can't download Fractal Terrains as it appears as a "Game" site! :-(
