Can I use .htaccess to prevent visitors from getting images

Wordpress as you know (I assume) uploads all the site images and media to wp-content/uploads/...
The problem is I have images I want to prevent any visitor from accessing directly, so I am thinking it is possible to set an .htaccess rule to possibly prevent direct access to anything within the uploads/ path. I'm very familiar with the file but I only know how to copy and paste in .htaccess, would love to learn more someday but not even sure where to start with it so if you could paste necessary code that would be extremely helpful.

Thanks in advance!
