Optimize images before uploading?

Checking my Nexus 5 as a reasonable current / modern data point, I have:

  • 667 jpg photos, 1.21 gb = 1.85 mb each on average
  • Largest 4.5 mb
  • Smallest 1.3 mb

If we bump the default max upload size from 2mb to 3mb that covers 624 (94%) of the photos on my device. That seems fine.

I think that’s a reasonable default for V1 and covers us OK … we’ll need to figure out some fancy resizing thing for post V1, since

  • phones will eventually have 10 zillion megapixel cameras, and every single image they save will be 5mb to 10mb+.
  • the worst-case “noisy image” photos will always be unusually large, e.g. my set of 5 / 667 images that are 4.0mb+ outliers.
