1. Create album. I created a Flickr album. I upload images to this album that come from my Growth Mindset memes blog. The Flickr album has a specific webpage address:
2. Create show. To create a slideshow from that album, I just add /show to the end of the album address:
3. Customize embed. To embed the album I click on "Share in the upper right-hand corner, and then "customize" so that I can adjust the widget of the slideshow to make it fit nicely in the very narrow blog sidebar.
4. Copy-and-paste. I copy-and-paste the resulting HTML code into the HTML view of the blog sidebar widget.
Now that slideshow automatically updates whenever I add a new image to my Flickr album!
I've embedded a 400-pixel-width version of the slideshow here. :-)
