Private member image upload/ gallery

Hi. I’m new to anything more complicated than the basic Wix interface, but here’s what I need to do.

I need registered users to be able to upload single or multiple images to my website. They and only they can then view these images in a page called “My uploads”. I then want to access these images, alter them, and then I will reupload them to the member’s viewable private page “My altered photos”.

I’ve tried Wix’s file share app but this only allows ALL members to view ALL members uploads as far as I can see. I want only the person who uploaded (and me) to be able to view that photo, and then only that user view the altered photo.

I’ve started looking at Content Manager, Collections, Datasets etc but I don’t want to go to far into that if it won’t do what I need. So any advice of easiest/best way to do this?

Thanks in advance!
