If it wasn't clear before, you will only get the pink elephant when the hotlink protection kicks in (for example from the fusker sites)
I used the same htaccess as I posted above.
What the OR does is exactly like in the English language.
If site is "fusker" OR "usefulidiot" OR "hotlinker2" OR "hotlinker3", redirect them to /test/hotlinkimg-d.gif
