How to use this file
A JPG of 4 GB exercises the same path when the format does not matter: web-server and PHP limits, proxy timeouts, memory, and whether the stored size is exactly 4 GB.
At this size, reading the whole body into memory instead of streaming it fails fast. For everyday tests, smaller files are enough.
This is a dummy JPG of exactly 4 GB. The contents are a placeholder for size and upload tests, not a finished file.
