Sorry to be a bore as this has surely been reported. Every page with
images has this problem:
$ w3m -dump http://en.wikipedia.org/wiki/Portal:Free_software|grep mascot
Tux, the Linux mascot.
Tux, the Linux mascot.

In the past we campaigned for alt="..." for readers who do not
download images. But now we get it twice instead of none. Just as bad.

Why not just have alt="Image:Tux.svg" instead of repeating the
caption?

Or do something fancy in stylesheets for visual users, and leave the
basics non-doubled for non-visual users.

This doubled caption effect of yours means that you do not pass even
the most basic of web accessibility tests! (others yes, but not the
most basic.)
