Saving general images
Saving images with the GIMP DDS plug-in is a rather straight-forward task, yet there are some things that can happen that may cause confusion for someusers. Most importantly, when the image you are trying to save contains multiple layers. Normal 2D DDS images cannot contain layers in the same way a Photoshop (PSD) or GIMP (XCF) image can.

You might get prompted with a warning dialog that asks if you are trying to save a volume or cube map image, and that it can't due to certain properties of the image not satisfying thattype of image.
