When the mailing list reminded me of DW (I had already pushed aside the memory ;-) I had a look at the upload log. I found that when he uploaded a smaller version of my images (which he did quite often), he used the same name again, thus leaving the large version only in the image history.
As far as I remember, he should have renamed them to something like "foobar (small).jpg", and linked to the large version from that image page.
I asked him to do that, twice. Both times he relpied on my talk page that he doesn't understand what I mean. The Second time he ended with "Go away...". I'm not sure if *he* went away, or told *me* to go away, though.
Is there an official policy on that large/small image thing?
