Something tells me I am doing something wrong will try again
You are not doing anything wrong, there is currently a bug in the forum software that is causing a delay in images showing up in posts (even after approval by mods or Superusers). The delay seems to be random and can be a few minutes or a couple of hours. I have approved your images and hopefully they will show up soon.
The link provided in your latest post to the live BQM is probably more useful than the static images anyway.
EDIT - Just noticed it isn't a link to your live graph, just a snapshot but at least that can be viewed while the forum takes it's time showing the images.
