Trying to POST image into form from Admin side to User on main.js

Here is the Admin side where all the magic happens with posting on my Laravel app:

Admin POST

And this is what I am trying to achieve on my main.js for the admin side, I want it to Post the Image to the sql database and be shown on user side:

Main.js

This is what it looks like when trying to POST from admin:

It is incorrectly shown because it is incorrectly written I think.

and the following is what is inputted into the database from the main.js, and its as far as I can go :(

this or something like this
