Small corrections- just in case anyone should need a thing like this. It has to be:
Options +FollowSymlinks
RewriteEngine on
RewriteCond %{HTTP_REFERER} ^
http://(www\.)?fusker.com(/)?.*$ [NC,OR]
RewriteCond %{HTTP_REFERER} ^

RewriteRule .*\.(gif|jpg|jpeg|bmp)$
http://neighbourhoodgirls.com/ggg.jpg [R,NC]
Not really sure how importent that [NC] flag is, but...
Ya, it really is odd Cleo. Thats why I couldnt figure out why my first one didnt work, cause the opposite worked fine.
