Install forum banner

[Rebel]

I have a forum banner to install. I did some checking on how to do this, but run into something odd.

I will tell you I just bought this forum off a friend and it has the old mybb logo still on..

Opening the ftp all I see are files, I did open the public_html and just more files.

I don't see any forums in there.

I have one active forum and one test board..

In all those files under 'images' I do see logo.gif

Can I delete that and add my logo.png file

Thanks..Ron
