All right, here is what you originally posted (I added spaces in the IMG tags so the typed part will show up):
[ IMG ]http://www.flickr.com/photos/36143764@N02/3339907177/[ /IMG ]
What you should have is something more like this:
[ IMG ]http://farm4.static.flickr.com/3657/3339907177_76259025d8.jpg?v=0[ /IMG ]
Which you will give you this result:
When you put the link inside the IMG tags it needs to be a link to the photo itself, not to the webpage that the photo is posted on. Look around and you should find an option to "Link to this Photo" or something like that, or you can do as I did and Right Click the photo, click "Properties", and use the information there as the link.
I don't use Flickr, but Photobucket gives an option that will give you the complete IMG tag without you having to do anything at all. I'm pretty sure that flickr will do the same. See picture:
