You have a large number of Flickr photos and albums. You have added tags to all your photos and want to create a link to a slideshow of photos containing a particular tag.
Solution: Perform a search of your photo stream for a particular tag. When you get the results copy the URL to a document. In the copied URL add ‘show/‘ after ‘search/‘
I searched my photostream for the tag ‘penguin’
When the results appeared I copied the URL
I added show/ after search
Now when you click on the link you will see a slideshow of all my photos with the tag ‘penguin’
