This is basically a notification of work that I'm going to do soon.
I noticed that one of my images (Moment_arm.png) was still in the upload
directory but had disappeared from the DB. I wondered if this was a
common problem. I checked using de:, because it's a bit more manageable.
I found that out of ~5200 images, more than 60 had no DB entry, not
including about 15 images that somehow were uploaded with an initial
lower case letter. There were maybe half a dozen valid DB entries with
no attached image. I'm going to write a script which reconstructs the
missing DB entries, and I'll run it on each language. I imagine the
reconstructed entries will be attributed to a user called "(unknown)",
or some localised equivalent.
