A while back, before I purchased LR3, I uploaded a few hundred photos to Flickr. Since, I received comments and fave's on several of them. However, I want to update them. Many need a little cropping done, others need to be adjusted, and so on. Now that I have LR3, I can manage my pictures on Flickr quite well, but how to I sync it with these pictures that were not originally added in LR.
I should mention that I have these photos in Lightroom, they are just not synced up with those on Flickr.
I know this is a little bit outside the normal questions on this site, but I think it is still within the bounds.
