I couldn't really use this block on a website. But it was a useful block for me to just examine and see how it works as a developer.

Yes! Does the job. Simple as it gets.

You can also embed your gallery directly into your site using the html provided by flickr. That gives you more options such as speed, size, etc. It also takes advantage of the 'full screen' feature on flickr.

This is ok. Doesnt update, (even if you choose latest rss feed). Can't manipulate the photo tiles. they show up in a list of one photo at a time instead of making two or 3 columns. My biggest frustration is the not updating part.
