Sorry for the delayed response. It was a holiday weekend here in the US, which slowed down our response time to our free extensions.
As to your issue, there wasn't actually an image attached to the post. After you upload an image, you need to click the green arrow to actually insert it into the post.
Even with an image though, the issue is likely a CSS conflict between our styles and your template. We'd need to see the actual page with the problem to determine what CSS is conflicting (we can't tell that simply from an image). If you can post (or private message) a URL, we'll gladly take a look.
Thanks,
Alex
