Done in revision 7607.

I've heard of TGA, but never of DDS.
TortoiseIDiff supports all the formats which are supported by GDI+
(installed by default on XP and higher, redistributable dll for win2k).

I've never used DirectX - can you maybe give me some pointers on how to
use the imaging functions there?

You don't need a bat file (which starts an ugly DOS box), just write a
vbs or js script. And if you do, please send us that script so we can
put it into our 'contrib' folder for others to use too.
