I've now fixed the message (there may be image formats even the external
converter can't do, and in that case the message was wrong), and I also
fixed it so that it works (i.e., you can now visit .webp files from .zip
files).

Fixed now.  :-)

So I think everything here has been fixed (mostly), so I'm closing this
bug report.
