A quick addition to Kitz work, add your TBB image like so. I've added mine in connection.htm, Open it in a text editor or whatever you prefer.... leave for the moment.
Now web browse to your TBB monitor page on the TBB site. Under your monitor image, click on 'Share Live Graph', Copy the link under Large Graph.
Now back to the editor,
Below <div class="graphs"> add the link. It should end up like this.
<div class="graphs">
<h2>TBB Latency Monitor</h2>
<a title="Broadband Ping" href="https://www.thinkbroadband.com/broadband/monitoring/quality/share/6e567f1077924e50f24ca309ba78976a"><img alt="My Broadband Ping - QP IPv6" src="https://www.thinkbroadband.com/broadband/monitoring/quality/share/6e567f1077924e50f24ca309ba78976a.png" hspace="20" /></a>
<h2>Connection Speed</h2>
<img alt="Connection Speed" src="connspeed.png" hspace="20"><br><br>
<h2>Bit Loading</h2>
<img alt="Bitloading" src="bitloading.png" hspace="20"><br><br>
</div>
Note that in the example above there is a hspace="20" towards the end of the TBB line, this is to bring it into line with the other images.
Save, open the connection page in your browser and you should have your TBB image, if you've got mine you've copied the example!
