By inverting the original MASK MAP (used for masking the image), and putting it
into the 'Transparency' Map slot we effectively make the area the image will
occupy opaque. The white part of the mask keeps the rest transparent (as in
having the transparency colour slot set to white).
Note: You can have any colour background for the image too! As the
'Transparency' Map is controlling the visibility of the image, any coloured
background simply will not show, this means you do not need to mask the
image at all, you can apply it as a 'Bitmap' map rather than a Mask
map.......bonus!
If you're lazy like me you don't even need to create an inverted mask either, use
a MASK Map and leave the 'Map' part blank. Put the original Mask into the Mask
slot and use the handy 'Invert mask' checkbox...........easy.
