Grrr, I hate Adobe's implementation of the integrated flickr publishing tool.
It's nice until you change something with an image that you have already published (on flickr). Then there's no way
you can prevent the re-publication of the modified version. The only thing that LR3 allows as an alternative is to delete the image from flickr (with all views, comments etc.)
