Babylon, I didn't realize until now what it is you're trying to post. I'm pretty sure the problem you're having is that TTtrader does not support embedded charts!
Try this URL instead of the one you've been using:
"Another problem that has surfaced concerns bandwidth usage. Many users have found a way to bypass the MyCharts interface and use direct paths to their images in message board posts and web pages. The problem with this is that if our allowed bandwidth is exceeded this also incurs additional costs from our hosting company...and at a much higher rate per MB than extra storage. When people directly embed their charts into messages and web pages, every person who accesses the message or web page downloads the image(s) to their computer, whether or not they are still interested in seeing it. We have already had days where the bandwidth usage spiked to nearly double the daily average allowed by our host due to a handful of charts posted to a message board in this way. We will be stopping the ability to do this, and encourage all users to post MyCharts links (rather than the images themselves) onto message boards and other external sites in the future."
