Heres a shot in the dark.

I was wondering if we can change the login panel. Rather than it go onto a new page could this be done as a pop up. I've attached a photo.

So the popup box would be like when you attach the photo.

Simon, if I understood your question correctly, you are referring to the login-panel of this forum.
In that is so, the question really concerns a different piece of software altogether (phpBB).

Frankly, I have no idea whether or not this is possible.
Perhaps phpBB's own forum would be the right place for asking the question.
