Ok thanks, topic can be closed now.
That's not your avatar, that's your sig. And yes, it's too big. ;) Take out the phpBB quote stuff, and just quote the lines together, if you like. Something like
[i6c449f7cc7]blab blab blab blah... - johnjimjones
me me me me me me... - TigerShark
The avatar is way too big. Make it smaller or everyone will block it.
