I usually share posts only with specific Circles of people I know. If you're here, it might be because I shared a link to a specific album of photos, but I don't know your Google account to be able to add you to my Circles.
If you don't see anything else here, first try signing into Google. If you still can't see anything but this post, it might be that I don't know your google account email, so I don't have it listed under one of my Google Circles. Either let me know your google account email, so I can add it, or edit your own Google account settings to add the email address which I do know as a secondary email on your Google account.
You may also join Google+ if you want to, and maybe ask me to put you in a Circle like Friends or Family. If you put me in a Google+ Circle, that's one way of alerting me to your existence in the Google+ system, so I can add you.
