I think it is a question of the aims of inkscape, If you are more interested in
building on the active developer community then the link should probably
just be deleted, as the link to the main downloads page is quite prominent
on the main navigation

I think the designer intended the link for a more end user friendly one click
download button (ok, they have to click another at sf) where they didnt
have to decide which package to choose. Download now links are becoming
quite popular as a means to provide the user with the quickest and easiest
way to provide the user with the product, http://www.mozilla.com/firefox/
would be my example. users looking for a download now link are expecting
this behaviour. users who do not want .exe / dmg also expect this behaviour
and look to the navigation.

I think adding a link to http://inkscape.org/win32/win32buildnotes.html to the
windows development builds section in the downloads page would be
useful in attracting more windows developers. I also think the build
environment is probably the most off putting, but thats another discussion

anyway, its to discuss stuff like this that i posted the site for. if its popular
concensus / Im told to, ill change the links

As for the disabled images, cheers, Ill add that to things to work on
