This code searches flickr for any images tagged with both 'black bear' and 'wildlife' and puts them into the following slideshow.
If you make up your own unique Flickr tags you can quickly put a slideshow of your own images on the web or on a blog. If you tell your friends what the tag is, they can also add photos to your slideshow if they have a Flickr account.
Alternatively you can make the Slideshow viewer just look for photos from a particular Flickr user. You can look up your flickr user_ID with idgettr.com. In the following code snippet and slideshow you can see only MY images tagged 'black bear' and 'wildlife'.
