profile image and covar image with laravel ajax database

I have a profile page, I want to use the Laravel language, using html ajax, I have a personal picture, I want to change it as in the pictures, but without refreshing the page and also the covar image is the same story as the profile picture

In using covar image, there is a costume that changes the image and after downloading it turns into a costume that either saves the image or cancels and returns to its natural state

Pictures, you will see what I want
