i have a file ./models/Image.js

const { Schema, model } = require('mongoose');

const imageSchema = new Schema({
    title: {type: String},
    description: {type: String},
    author:{type:String},
    filename: {type: String},
    path: {type: String},
    originalname: {type: String},
    mimetype: {type: String},
    size: { type: Number},
    created_at: {type: Date, default: Date.now()},
    authorname:{type:String}
});
module.exports = model('Image', imageSchema);

I have another file ./models/User.js

const mongoose = require('mongoose');

const UserSchema  = new mongoose.Schema({
  name :{type:String,required : true} ,
  email :{type  : String,required : true} ,
  password :{type  : String,required : true} ,
  date :{type : Date,default : Date.now}
});

const User= mongoose.model('User',UserSchema); 
                                            
module.exports = User;

and a function inside routes/user

router.post('/upload', async (req, res) => {
    const image = new Image();
    image.title = req.body.title;
    image.description = req.body.description;
    image.filename = req.file.filename;
    image.path = '/img/uploads/' + req.file.filename;
    image.originalname = req.file.originalname;
    image.mimetype = req.file.mimetype;
    image.size = req.file.size;
    //image.authoremail= User.req.email; // what should i do here
    
    await image.save();
    res.redirect('/user/feed');
});

What i want is to put users name and email inside image schema so that i can compare it for later purposes for example in a page of dashboard user is only shown the picture he/she has uploaded but inside page 'feed' pictures of all users is displayed with there respective name
