Nope.

Viewing the page source shows a superfluous "http://" preceding the picture's url. The doubling up there is likely the reason the picture is not showing.

This can happen when inserting an image, as the text entry input for the url already contains an "http://", so if that is also present in the url one is pasting in, two can result. Either clear the default "http://" or don't include "http://" in the url you paste into the text entry field.

I also suggest making use of the "Preview Post" button if you're not already, as that should show any problems before the reply is officially posted.
