While uploading an image there should be an option to either select an existing category or create one
I'm working on this currently, should be available sometime within the next two weeks :)
Merged as of da6e03587852191e8c353be1d5bc60cc3c863cb7 for both single and multiple upload. Should roll out normally by next Monday.
