Thanks for your replies.
I am new to administrating my own forum, so I am in la-la land at understanding everything....this included.

I wish the silly "prtscrn"
would work on my keyboard and I could show you exactly as it appears in the FTP program, but it doesn't.
This is the path that I am using----public html--styles--prosilver--imageset. The FTP transfers it, but where, I have not idea as it will not show up.
Another path I have used is this: public html--www--styles--prosilver--imageset. That didn't work either.
Apart from doing these things, I have no idea what to do next.
As for phpbb 2 appearing in the public html files and folders , I haven't got a clue. You would think if I had that version on my forum that would be fine. But I don't !!!! I have 3.0.2. So shouldn't that version be appearing in there ???
