Can you please provide your site URL and the details of the client (browser, os, etc)

ok, you have a 412 error on upload.php:

f0
Precondition Failed
The precondition on the request for the URL /upload.php evaluated to false.
0

This is the first time that I heard of this type of HTTP error. I'm investigating it.

Try this: http://wordpress.org/support/topic/plugin-nextgen-gallery-http-error-412-while-uploading-photos

Add this code to your htaccess file:

<IfModule mod_security.c>
   <Files upload.php>
    SecFilterEngine Off
    SecFilterScanPOST Off
    </Files>
</IfModule>

It works now!

Thank you very much, Rodolfo.
