Tagman, please excuse me if you tried the following process already. The url must have been corrupted somehow. Please try sharing the album again with someone (or yourself using an email address other than the one you used to sign up for snapfish) and check the box to have the email sent to you as well. Get the email, go to the album, copy the url and paste it into a post again.
Hopefully that will work.
Thanks for going to all this trouble to share with us.
