The point of generating images during the send is to use the power of the PC and generate better images. Generating them as greyscale is done for the same reason. The fine tuning of this was done by @NiLuJe as it is not something that I care that much about. From memory, the greyscale images are smaller than those generated by the device, but, it has been a while since I checked.
All the options have tooltips. You might want to check what they say about quality and size.
