Durring the process of figuring out why I was getting all these 'missing images' bugs, I figured out how to make custom images and expand on the humanoid and alien races that exist. I cooked up several human icons based on old public domain paintings, I've 13, and the resources to make more. I also figured out how to impliment hull images for the galaxy map. In my opinion the 'hull' should be replaced with a person, or at least replaced with the word 'icon'. I'll experiment later to see if an animated gif is possible, maybe a Niel Armstrong in a space-suit for "humanity" and a green man for an alien, and maybe a roach for the bug aliens, etc.
I had first contact with an alien race recently who all looked like captain Sulu from Star Trek. . . . least to say it was amusing, but odd.
As alien races are further developed, it could be helpful to sort them by humanoid, insectoid, jellyfish-with-a-fez, energy-based, etc, with their own folders in the Race's images folder, as well as giving numerical value to describe an alien a race's language, culture, and physical anatomy; possibly on a scale from 1-50, etc. The overall effect is that species that are more alike, would be much easier to communicate with, and engage in diplomacy with. Other species, say telepathic ooze, might have considerable trouble interacting and communicating with an energy-based life form who lived as within the matrices of crystalline structures. This is especially so if the ooze find the crystalline structures quite tasty.
