On the other hand, the K3 JPG files are a big no-no, and will probably screw up everything if you try to be clever and just rename them as .png without actually converting them to PNG8. If they're still using the .jpg file extension (or .jpeg [actually, anything other than .png]), the hack will discard them automatically.
