Hello!
I\'m using RSGallery2 1.10.11.
In den backend the zip-upload is working fine.
But when i try to upload a zip-file from the front-end (logged in as admin), i get the following error-message:

Warning: Missing argument 3 for importimage() in /srv/www/htdocs/web110/html/administrator/components/com_rsgallery2/includes/img.utils.php on line 129

Notice: Undefined index: extension in /srv/www/htdocs/web110/html/administrator/components/com_rsgallery2/includes/mimetype.php on line 190

What does that mean?
