This GIF was automatically created by Google+ photos, when I uploaded a time lapse sequence of 16 photos taken every 2 minutes as the sun set tonight. Ok that was easy BUT it only used the first 5 photos :) and then I wanted to share the gif back in Blogger! Sound easy, well I could find anyway to even find the link address in googl+ photos. I had yo come back into the new post dialogue in Blogger itself and then use to insert a photo from Picasa Web Album!
I suspect google have a few things to fix/finish developing, well i hope they are planning too.
