Ahhhhh free photos. After all it's easy right? Yet the requesters for free photos can't go out and make their own. I work in Government where I often have to give photos to people outside my agency to use. Often they very enthusiastically ask how I would like my photo credit to appear. Enthusiastically they ask because after all they are doing me a great service by getting me published and it is within their power to add my name.

My response. Please don't put a credit at all.
WHAT! WHY NOT? they ask in shock as their benevolent act is rejected.

My Response. I don't wish to attract more people looking for free photography.
