How to save the image for laravel

[dr-roshyara]

Could you please write an example how to save image with laravel framework?
I fixed the laravel route route('/avatar/upload') with post method but and gave the url /avatar/upload but it did not work. neither it worked without url
Can you please write in detial how to give a saving url or post method so that i can catch in php.
the best would be if you could write how to use with inertia.js form.
