Just a quick note though… In the interest of front end agnosticism the socialize:cloudinary package lacks any kind of autoform integration like many of the other cloudinary packages, so if you’re looking for something that has this, then you’ll want to find another solution.
As far as saving them to the database the main thing you want to worry about is storing the pubic_id, that way you can pass it to the Cloudinary.url() method. This could be just as a field on the user, or it could be in an images collection that is linked to a particular user.
In the coming months the plan is to have a couple more socialize packages (Photos, and Albums) for dealing with saving and displaying the information returned from cloudinary. Right now though I’m working on porting the other packages in the set to be used with React Native so it may be some time yet before I get to them.
as @kaiyes said, I’m pretty active here, so if you have any questions or need help, just let me know.
