I knew it was not the best solution: all i wanted was to validate. But
an empty alt or maybe just "image" is fine by me too.

I've tested my patch only on [[big_image.png][small_image.png]] kind of
link (maybe that's why).

Ok, those 2 last hunk should complete my patch I guess. But what I'd
really like is a way to set a alt as a user. Maybe something like this:

   [[big_image.png][small_image.png|my picture is cool]]

What you guys think? I'll look what i can do and try to make it work for
anykind of <img> tag that can be generated.
