Editing the DDS files for texture? Help?

I recently downloaded a NOICE model, but alas the texture sux, I want to edit the texture, in gimp, but the texture file is DDS not bmp or jpeg.
How can I edit it?

Paint.net can open DirectDrawSurface and (I think?) photoshop as well.

Photoshop requires a .DDS texture plugin to import.


Thanks you guys, i got it done with paint net
