EDIT: Is it possible that it has something to do with the browser one's using...?
Sorry to bring this subject back, but...
So that you don't think I'm crazy (and for my own sanity), here's the screen I get when using Firefox (and that I've always got since using Picasa):

As you can clearly see, you can only pick one photo at a time (and you can't shift/ctrl+select any more files...). It was a pain to upload an entire album.
Afterwards, I tried with Explorer and when I got to the upload menu, I got a message saying I had to install "Picasa Web Albums Upload Control".
I did so, and voilà:

The menu is now quite different and I can pick all the photos at once. Finally.
I know I'll never use Firefox again when dealing with Picasa... And sorry for wasting your time.
