🚀 go-pugleaf

I have a class here that is a piece of a project and I'm just about to
scream! :<  The code seems to do absolutely everything but what I thought I
was coding it to do. :<  Can you take a look and see what I'm doing wrong to
have the right hand side panel be painted exactly like the left hand side
panel, even though it's totally another class that is supposed to have an
image in it?

I think I'm doing something very wrong with my last method, but I just don't
know what?

Any help would be appreciated.  Thank you very much.
