Take your website off the internet.

If you don't want to do that then there is nothing you can do about it.

Could you do it on .htaccess file instead of php so that users can not access image site ?

RewriteEngine on
RewriteCond %{HTTP_REFERER} !^http://(www\.)?localhost [NC]
RewriteCond %{HTTP_REFERER} !^http://(www\.)?localhost.*$ [NC]
RewriteRule \.(gif|jpg)$ - [F]

And the site if let user view the image, in other words, what they view and what they can
download unless don't putting it on servers

You can prevent hotlinking

RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http(s)?://(www\.)?yourdomain.com [NC]
RewriteRule \.(jpg|jpeg|png|gif)$ stolen_from_my_site.jpg [NC,R,L]

edit:
Actually rowby's solution is similar - I'll leave mine since it gives you the option of redirecting to another image that you can make that says Stolen from mysite.com just to piss the other website off. (but Rowby deserves the main credit)

You might find this useful. The strategy is to make it impossible for the image to have a direct-to-file URL.
