In a previous posting I mentioned Flickr slideshows, I also mentioned that WordPress.com blogs couldn’t use the code, as WordPress.com stripped it out.Well look here I have embedded a Flickr slideshow into this blog entry. I used Vodpod to do this.
Vodpod videos no longer available.
Edit: had a few issues with this blog post, hope it is working now.
Edit 2: think I may have solved the problem.
