HG,
There is more than one way to post an image. In your message box where you type, there is a yellow box with what looks like mountains next to the last item which is the "quote" box. Every image in your album has a url, or "image address." The easiest way is to go to your album and right click on the photo and select "copy image address." Now go to your message box here where you type, and click on the yellow box that will say "insert image" when you scroll over it. Click on it and paste your image address in it and hit ok. It's as simple as that. It will embed right into your post.
If this is the one, he's a good one:
