Having looked at the code now (!), it looks like user/pix.php is designed to do exactly that.
My Opera browser is definitely refreshing the avatars on every single visit, though, so I'd like to trace the reason.
May I ask why the line
doesn't have anything after the colon? I've not seen Pragma used like that before and I wonder if Opera is interpreting it as a no-cache directive. All the other headers are perfectly normal and tell the browser to do what I'd expect....
