Windows 7 Tip: 
Picsviewr is new web service which allows you to make a Slidshow or Presentation of your Flickr photos. It seasy to use, you don,t have to create a new acoount or not to upload your pics there too. You just wna to put your Flickr username there. And Picsviewr will provide you the link of your slideshow. It so simple.
It works really simple, there is no need to create an account or configure anything. All you have to do is enter your Flickr username,
Looks really simple even for newbies. Nice find man.
You should know that Picsviewr is using existing widgets without permission, even after the creators of the widgets requested them to stop using it.
Their lack of ethics is an embarrassment.
