I was following the documentation and noticed that the 'Field configuration' section had an error. Looks like the 'Field configuration' setup syntax was the same as the 'Global configuration'.

So i corrected so new users dont get it wrong.

Test plan Was able to Insert images correctly after updated syntax.
