Hi Janet,
Sounds like a great project but looks like the link to your flickr photo did not work. Here are some simple instructions: go to your photo in Flickr and click the arrow button in bottom right corner to "share" the photo. Select "BBC Code" and a medium size, then copy the link provided. Now create your message here on the forums and simply "paste" your photo link into the text box. Use the preview button to see if it worked. That's it! Also please make sure that any photos you want to share are made "public" on your Flickr page.
