You need to have photos in your own Private Photo gallery before you will have access to the Swap Access feature.
If both members (you and the profile you are looking at), have pictures within their respective private photo galleries, then you can request Swap Access to these photos.
Once you submit a swap request you will see that you have a pending request when you view that members profile.
When someone requests a swap with you, you will be notified from within your My Photos page via the Photo Access Manager.
When you approve a swap request, both members will have access to each others Private Photo galleries for 48 hours. Please note that a swap request can not be cancelled or undone. A swap request will expire automatically after 48 hours.
You can view all your current private photo access from within the Access Manager at any time.
