you need to use the URL of the image and not of the flickr page ...
example:
not this
http://www.flickr.com/photos/7360827@N05/518468387/
but this URL (the actual image url)
http://farm1.static.flickr.com/208/5184 ... a65f8e.jpg
if you control-click on image you can open in image in a new window and see the actual image URL.
Using this URL with the code image code ... will show up like this:
![Image](http://farm1.static.flickr.com/208/518468387_dc8da65f8e.jpg)
