Should these privileges work for my new mysql user

Question

I want to make a new user for mysql that my website should connect with.

My website uses the following functions:

SELECT, DELETE, UPDATE, INSERT, INNER JOIN.

My website is also using mysqli with bind_param/prepared statements, and also supports image upload, with a crop function.

So should the following privileges work for a new user in order to use the stuff above

SELECT, DELETE, UPDATE, INSERT, FILE.

And I am not sure if I need the "EXECUTE" and "INDEX" privilege.

I already have a root user which I use to change around in the database with, I only want this new user to be used BY my website.

ALSO, I am creating this user using the program Sequel Pro, should I manually run a "FLUSH PRIVILEGES" after adding the user and setting privileges or does Sequel Pro do that for me?

Thanks in advance,
