You have some html code for image display embedded in your link.
Flickr is not the problem. See?
Get a simple pointer for your image. In flickr, this may require some trickery, as the light box is an application that masks the actual image name. Pick "all sizes," click on a size, then right-click (or mac equivalent, I think ctrl-click) to get the image info. Cut and paste the image name into the message, and use the img button.
BTW, this image
is actually copyrighted. Use TinEye to look it up -- a lot of sites have cloned it.
