PD stands for Public Domain, a term used for creative images where the copyright has expired. If a photo is in the Public Domain then there are no limits or terms that specify how the photo can be used. Public Domain images are generally not as well shot as stock photos or custom photos but can provide you with what you need.

I am a publisher and entrepreneur in the stock imagery field. I focus on providing knowledge and solutions for buyers, contributors and agencies, aiming at contributing to the growth and development of the industry. I am the founder and editor of Stock Photo Press, one of the largest networks of online magazines in the industry. I am the founder of Microstock Expo, the only conference dedicated to the microstock segment. I created several software solutions in stock photography like WordPress plugins. Plus I am a recurrent speaker at Photokina Official Stage, and an industry consultant at StockPhotoInsight. I am passionate about technology, marketing and visual imagery.

  1. I have found many, many sites where the quality of the images equals those of paid sites.. You just need to know where to look..
