1) vbgallery >> administrators >> Can upload images directly from server = enabled (I'm an administrator, first user of VBulletin) Can upload images = enabled
2) in the folder /gallery/users there is a HTML file (always).
And when uploading (file is uploaded, but page upload.php has not been submitted) is complete (If i may believe the flash upload "1 file uploaded, waiting for you to hit submit below") there is a map with the name of my users ID. This map is empty. CHMOD for users is 777 aswel as the map of my user ID.
