Additional Airline Images

[kevinelliott]

@baspete First of all, thanks for this fun split-flap departure/arrival board. I appreciate the work that went into this.

I'm customizing this for my own needs, and realizing that you have implemented the airlines images as a fairly limited sprite.
Where do you usually get your images for each airline?
Do you happen to have a process for adding additional airlines?
Do you have the original pieces available by any chance? (psd, etc?)

Thanks in advance.
