enabling hotlinking only for one domain till the rest are still protected...?

[Fking]

have disabled hotlinking doing this in my main .htaccess file

RewriteEngine on
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^{http://domain1.com/.$} [NC]
RewriteCond %{HTTP_REFERER} !^{http://domain1.com$} [NC]
RewriteCond %{HTTP_REFERER} !^{http://domain2.com/.}$ [NC]
RewriteCond %{HTTP_REFERER} !^{http://domain2.com$} [NC]

RewriteRule .*.(jpg|jpeg|gif|png|bmp)$ http://domain1.com [R,NC]

infact this was build automaticaly by cpanel

well now i want to make the hotlinking allowed for domain2.com
how?
