[Flashr] tag search results in slideshow

[Doug Marttila]

Hi Gloria,

I just posted source for connecting a flash slide show to flickr...

http://www.forestandthetrees.com/mashupTalk/mashupCodeExample/index.htm

Take a look at the FlickrPhotoGetter class. and the getPhotosByTag method.

The source should basically do what you want.

Good luck

Doug
