How to upload excel sheet image into database in php or in Laravel

I wonder how to upload excel sheet image into database in php more accurately in laravel.

For example i have an excel sheet which contain product information such as product name, price, product images etc.

Now how do i upload that image to server. I know how to upload normal text such as product name, product price etc. but not sure how should i upload the image. I did googling and check here and there but i didn't get any useful information

Can anyone give me some hint or suggestion or solution? Thank you
