You can attach an image - just do it while previewing your post (you'll see a field where you can browse to an image file).

The ERR column means that a packet was lost - on a non-responding hop, you'll always get ERR's (no responses). On the final destination, if it's showing up but you occasionally get an ERR on the final destination, then that means you're losing packets - look back at prior hops for packet loss.

Post an image and we'll have a look to see if there's anything we can see from that.
