images still pointing to localhost

after having completed the site locally on MAMP i moved the whole thing to Plesk, I
– moved all folders to the new server
– created a new database with the same credentials as my wp-config setting
– replaced the localhost to my new web domain address in the sql file
– imported the sql into the new empty database in Plesk

everything works fine except the images keep pointing to the localhost, even though i replaced it with the new domain address in the sql file.
I know there are a lot of posts out there concerning this issue and i have tried recreating the database and importing over again but the problem persists.

I must be doing something basic wrong.

one further question: in my sql file, what exactly does
Machine: https://www.equalminds.be:3306
stand for? This used to be Machine: localhost:3306. is it wise to also change this?

Thx
