I was looking for a .dds conversion program with quick and simple operation, and thought this might be of interest to some:
DDS Converter. "Version 1.0 is simple image converter for DirectDraw Surface (DDS) images, it can convert DDS images to JPG/JPEG, PNG, BMP and TIF/TIFF images. Program can support batch conversion." http://www.ddsconverter.com/
bobbystahr recommended IrfanView, which does far more than DDS Converter. http://www.irfanview.com/
Yeah, I find I use irfan more than PS nowadays for mundane conversions.
