I'm the admin on a gallery, but now I've got this problem (search didn't helped)
I want to be the only one who can upload MP3's, so the users can listen to them, but they cannot upload MP3's theirselfs... If I upload one, and then go to config.php, where I set ALL (at the music field) to none, the icon of my uploaded MP3 is gone.. All I get is a little square, so it is very hard to click on it... Is there any way to set the permissions about uploading MP3's? Thanks!
As it stands, no. You cannot set filetypes allowed by groups or users.
If you allow users to upload, they can upload the same filetypes as you.
