I think the assumed path is:
http://en.wikipedia.org/wiki/Wikipedia:Upload
then clicking second link to
http://bit.ly/1a5s5O
Then in that drop down there should be the things you are looking for
under "freely licensed" or "public domain".
The dropdown at
http://en.wikipedia.org/wiki/Special:Upload is not
that user friendly, but it's not that easy to get to either, unless
you are familiar with special pages and/or have bookmarked it. I think
the assumption now is the only people using that form would be expert
users that might just prefer manual tagging and not going through the
little path for newer people.
Maybe it's still linked to prominently somewhere forgotten though, no
doubt... :)
