Please follow these rules and nobody gets hurt:
1. Always credit and note me.
2. No commercial use without asking first.
3. No political or religious treatment of the images (the second also includes atheist propaganda against the religious beliefs of others); this means these stock images are not meant to be used against or in favour the beliefs of anyone, specially in the case of the U.S.A. don't use the images depicting donkeys, elephants or any other animal to cartoonize any political group.
It also includes PETA-like activism or messages against such activists; this obviously refers to pictures depincting animals but it's a general rule about controversial issues; i simply don't want the images used in propaganda of any kind.
4. No sexual/racial messages.

You can note this account, that's better than leaving comments but it's easier if you send the note to my other official account (which contains non stock material!) namely

As far as you follow these previous rules you can note me after you've used the stock material in your work.
