Image upload or camera, display image as the background of sketchpad canvas. The user highlights the area of interest. The app receives the sketchpad JSON.

options/questions:

1. We keep Upload File and drop Take Photo. On my Android phone, I have the ability to use the camera. This gives me native ability to switch cameras. Simplifies the app. Negative is that it's not obvious that this is an option and may differ from OS to OS.

2. Read camera dimensions, allow switch camera in the app. Advantage is that it's visible right away. Negative is that camera seems to be on all the time.

3. What to send in POST. the image? the JSON? both?

Ideal UX:
single image search option in navbar
presented with single sketchpad canvas right away. can draw and submit.
or can take photo/upload image which is then canvas background
