Something (maybe a web crawler?) caused lots of image files to be created here, each with all the transformations.
The files have no Author phid and no TTL, and no transactions or edges in the db.
It's concerning that we have objects created with no tracing about them.

The task: visit any code-path that can create a file, and add some note somewhere about the file being created:

• why
• who
• how

Add a flow to bin/files to explore this information.
