OSMC Installation

I was wondering which version of OSMC is the latest in the OSMC installer (Version 1,2 or 3 or the 06-.1). I am brand new to all this so sorry if its a stupid question.

Thanks,
Jon

1,2,3 are RC (Release Candidates) so 2015.06-1 marks the first stable version

Thanks!

Also how do I download pictures to it to use for Aeon NOx backgrounds. Do I have to SSH into it?

Unless you are using a source (SMB/NFS/…) that is visible in the file manager using SSH with wget would be the best bet

I would suggest something more along the lines of sftp by using Filezilla or WinSCP, of course same credentials as SSH (osmc:osmc)
