Yes?
Requirements:
The [name] field in your library needs to match the filename that's uploaded to flickr. For me, that's the default, though, I've had to stop Carnac messing with that on auto import by adding a [name]=removeright([filename (name)],4) rule to the folder in auto import options.
The keywords field needs a flickr tag on each file you upload. (You could use a different field, but would need to edit the filter accordingly in order for it to work)
You need to go to flickr and do a manual search, making sure you are only searching "your photostream". This will give you your unique stream number for later use.
Next, copy the text in the code box below, open the link manager and hit the paste from clipboard button.
<Link version="1.2">
<Item Name="Name">Show on Flickr</Item>
<Item Name="Action">1</Item>
<Item Name="Base URL">http://www.flickr.com/</Item>
<Item Name="Search URL">http:////www.flickr.com//search//?w=29865838@N08&q=[name]&z=m</Item>
<Item Name="Filter">[Media Type]=[Image] [Keywords]="flickr"</Item>
</Link>
Finally, you need to replace the number between "w=" and "@N08" above with your own photostream number you acquired from the manual search you performed earlier. It's possible that the "@N08" part could also be stream specific, so keep an eye on that and replace too if necessary.
Enjoy
