Can't create album or upload image with remote command (no GalleryRemote)

Hello,
sorry for my English.
I'm trying to make an application to communicate remotely with an installation of Gallery2.
Through GalleryRemote everything works properly. With what I've realized I can just log in and read the whole list of albums. If I try to create an album I get this error:

OK

I used a command like this:

/main.php?g2_controller=remote:GalleryRemote&g2_authToken=" & authToken & "&g2_form[cmd]=new-album&g2_form[protocol_version]=2.1&g2_form[set_albumName]=" & TextBox1.Text

Same problem if I try to upload an image. In this case the error is the following:

Can anyone help me??

Thank you.

Thanks for your reply.
I look uploadfy but do not understand how to interact with it in a stand alone application (net framework). You have indications about?

I also tried with galleryadd.pl and I can do everything ... except that specify the parent album of a new album ... is there a solution?

Thank you.
