Downside: We'll see slight changes in visual quality, and a few images
might break.  We've already tested this ourselves, but we'd love more
testing ahead of time to check for bugs so we can fix them early next week.

What should be tested?

- Uploading (a big) image and checking if it is broken?
- Checking if the quality of the thumbnail(s) is lower when uploading the new way? (When compared to uploading the old way.)
- Both?
- Something else?
