Hi Val
It's usually better if you attached the image directly to the thread (I've downloaded your version from smugmug & attached it for you)
To do it yourself, when creating your post
- Click "Go Advanced" below the quick post dialogue box
- Scroll down the page until you see "Manage Attachments" & click it
- In the windows that opens click "choose File" & navigate to the file you want to attached
- Click upload & when the upload is complete, close the window
- Job done
