Customize Oxwall Photo Plugin: No Albums, Just Photos. And Private (Adult) Photos for Paid Users

This is a Skadate+Oxwall website for Gay Adults. Our Free users can upload public photos. Now we want Paid users to be able to upload Private (Adult) photos that they can unlock for specific users who request those photos. We currently use: + the Oxwall Photo plugin ([login to view URL]) + Private Albums plugin ([login to view URL]) + And the Paid Membership ([login to view URL]) plugins but we need to customize the code to our needs. We want all public and new private photos to live in Oxwall Photo plugin. First, we need to remove the ability to create albums. Instead, all the photos should be together in “root” instead of an album. All Public and Private photos together in the Profile Photos Widget. Maybe internally there is a "Photos" album, but it should not be visible to users. On the Profile Photos widget all photos should be listed there rightaway without the need to go first to an album. We do not like albums. Another important feature needed is the ability to grant access to private photos with a per-user permission. Right now the "Pivate Albums" plugin it grants access to “All friends” equally and that is wrong. When chatting or viewing the profile of another user we need an “Unblock Photos” button. The uploader receive a confirmation for "grant access to private photos" or declines the request. This should work as a "friend request" with a ok or cancel message right in the notifications. If user grants access then all his private photos are now visible to the user who requested access. The users then gets a notification by Message system stating that he can now view all the private photos of user X. Also, we need a "Private Photos settings" page with a list of permissions granted to each users. Here the uploader can revoke access to each user individually. The link to this page should be located in the User menu on the top right corner. In the same menu with the Edit profile and Logout links. The website Administrator should be able to Flag a photo as Private (Adult) at any time. Some Free users might end up with Private photos, that is ok. They can have them and edit or delete them, but they can not upload new ones. + See UI screens in here: [login to view URL] + All current photos should remain intact. No photos should be deleted. + Private photos should not be listed in the Photos page. They should only be visible to users with permission granted by the uploader. + If there is more than 8 photos in the Profile photos widget then we need a "View more" button that goes to /photo/userphotos/username instead of the regular /photo/useralbums/username. There Here the user can see all the photos. + Clicking on a profile photos widget thumbnail should open the photo in the default Photo plugin modal window in place without page redirection. (as in /photo/userphotos/username, where you click a photo and the bigger version opens right there). Users should be able to navigate ALL photos within that modal window. By ALL photos we mean all the user photos, not just the first 8. + All strings (if any new) need localization (es-Es). The original plugin language should be Spanish (Spain), but it should be able to be localized in English (USA). We should be able to edit strings in Admin default language page.
