PHP Help (Plogger Gallery)

Hi all, firstly, I think you’re all great, wordpress is great and you’re all lovely people for helping everyone out.

Onto my problem, I have a wordpress blog (running 2.02) that I want to interate a plogger gallery into. I’ve followed the instructions At Phoenix Realm and have ended up with something like what i want : http://www.jonrouston.co.uk/plogger/

However, as you can see the header seems to be a bit replicated (top right hand corner) and clearly, the gallery appears three times. I tried editing the PHP myself, but am not very good at it, and it got worse!

Can anyone help?
Thanks in advance
Jon
