The FAQ states:
ShareAlike — If you remix, transform, or build upon the material, you must distribute your contributions under the same license as the original.
That makes sense - if I want to include a graphic under that license and modify it, then I have to make that modification publicly available under the same license. But does that apply to the rest of my code? Whether or not I include a modified or the original graphic in my application?
I have no issue with attribution or releasing my modifications of affected graphics, but I don't want to publish my code.
