I've seen it requested several times, so I compiles the osx64 binary and set up the tree and put it in a zip archive. To use, just unzip into your KSP install folder or any folder and run dds.py. It will work run from any folder if you point dds.py to your KSP install. Link: https://www.dropbox.com/s/5r29b8kt3p8nnau/img2dds.zip?dl=0
