I let my PRO account expire, so I have trimmed my PhotoStream to only 200 images. If you've experienced some missing images in your groups, this is why.

"... account stats currently come free with a $24.95 1 year pro account." How FREE is this? Duh!

EDIT: July 2013 - It looks like the 200 image limit has been lifted. However, I've moved on. So have a lot of others.
