Also it seems the SW wiki have ditched all their old race photo pictures in favour of drawn ones. No amount of searching around allowed me to find anywhere that had SW races listed with photo pictures thus I did not add many at all from there. If anyone knows of a place that keeps photo pictures on race profiles I'll happily add them in.
You can probably find them in the pages history, have you tried loading an old revision?
I would have to assume that would be for copyright reasons, I'm pretty sure a small thumbnail sized image taken from a screencap in order to show a character's appearance counts as fair use in the US, as long as used for non-profit educational or media use, I'm not sure about the EU though.
Maybe, or they just went for style points (I also prefer stylized drawings), because iirc using low res screencaps of character on pages that cover them should have no problem.
