Admin-created private content specific for a member

[khans]

Hi, I have a car buying service and am trying to add my clients’ purchased vehicle details (pictures, car details, window sticker, etc) to my website to allow clients to login and view this. The closest I have come to a solution for this is leveraging the members’ Wix functionality, but out of the box it only seems to allow member-generated content. After a tech support ticket, recommendation was to use wix code, but I’m not clear on how to put the code together. All I’d need, similar when building a generic webpage on Wix, is to a) add an images collection to the members page, b) display images by loggedin user, and c) then upload picture collections and associate them to a specific member. Any creative ideas or sample code that could achieve this?
