Pixabay.com - 30.000 professional public domain images
With almost 30.000 images, Pixabay.com has quickly grown into the largest resource for quality public domain images. This website consistently provides creative works - photos and clip arts - with all copyrights waived in agreement with Creative Commons deed CC0. Thus, images may be modified and no attribution or source link is required even for commercial applications. Furthermore, Pixabay's manual review process of uploaded images ensures both, a high quality standard and legal suitability concerning the public domain area.
Founded in January 2011 as a spin-off company of the writer networks Wizzley.com and Pagewizz.com, Pixabay has already become a mature community and source of images, supporting 20 languages and attracting professional bloggers, journalists, web-designers and any kind of creative worker from all over the world. In particular with the introduction of the "Stop Online Piracy Act" (SOPA) and other copyright-related bills (PIPA, ACTA), Pixabay received a remarkable boost of traffic, emphasizing the demand of free images on the web.
"Pixabay was originally developed to prevent legal disputes about copyright issues of images on our communities Wizzley.com and Pagewizz.com", so Hans Braxmeier, co-founder of Pixabay. After the successful implementation, Pixabay was consulted by third party webmasters asking for an API to access and search the image database from outside Pixabay and thus, to enable usage of those images directly on partner websites, as seen on Psykopaint.com.
As an additional means of communication for Pixabay's users, a multi-national forum was integrated in March 2012. Also, to reward particularly great photos, the Editor's Choice Award was introduced, resulting in a list of hand-picked, awe-inspiring photos, qualified for professional applications or - just as well - to serve as amazing desktop backgrounds.
The Future of Pixabay
"Pixabay intends to become the Wikipedia for great public domain images; the first website you visit to find images, when you need them", Simon Steinberger (Co-founder of Pixabay). And Pixabay is on the right track: a Google Pagerank of five and a constantly rising global Alexa Traffic Rank of currently 40k reflects the rapidly growing popularity of this image database.
