Offer to create (supervised?) image rotations if less than 5 images per label.
Jonathan Zwart commented
It would be nice to add other operations to achieve this too e.g. crop / reflect / add noise.

I can't take this 5 image limit because you refused one of my images. I accept it, but rather than make me rotate images offline and upload, offer the service to put an image at 15 tilt /rotation and get user approval, ideally with a "Yes do it without me checking to all of them" option.
