Have you checked for ownership or permissions problems?

I believe that the .png files are created using mythpreviewgen, which you
can run manually.  But I have never done that.

First thing I checked. Initially they were over there under the wrong user,
but I chown'd them to mythtv:video like they should have been. But it seems
to have made no difference.
I'll look in to the previewgen later today and report back, thanks for the
idea.

Scratch that.. picked a test one and while I did recreate both files, it had
no effect on mythweb. No idea why.
