Ah, the timing. After publishing the previous post, this happened within an hour:
As an update to the post about free storage, I’ve downloaded then deleted from my WordPress Media Library screensnaps that were waiting for homes in a post. A little over twenty megabytes so far. Still many more to do. I should be able to clear about forty megabytes of free storage space. But that change won’t register immediately at WordPress. So, keep standing by.
Also, I might not run any of them. But if I do, they’ll be scaled to half-Retina or below.
