How are image prices decided on PhotoDune?
Images sold on PhotoDune are priced based on their pixel dimensions. The more pixels, the larger the image and the higher the price. We offer multiple versions of each image so that you can purchase your desired file in the size that suits you.
Are all images on PhotoDune 72PPI?
No. Authors can submit images at any resolution. If the image you purchase is at some other resolution, you can change that without affecting the pixel dimensions or image quality. For more information on PPI, DPI and how to change image resolution, this tutorial may be of assistance.
What even is PPI, and how do I know what size image I need?
PPI stands for pixels per inch, and is a measurement of the resolution requirements of computer screens, printers and other devices that create or display images. If you're looking for an image to put on a website, you should purchase based on the pixel dimensions of the sizes offered on PhotoDune. However if the only information you have available is the physical size the image must be (in inches or cm) then the table below may be of assistance. Digitally displayed images are typically set to 72 or 96PPI, while high-quality print materials should be set to a much higher pixel density, because printers create images in much greater detail than a computer screen does. If you print an image at 72PPI and look at it from arm's length it'll look pixelated. If you need an image to print at 300PPI and you know it has to be 8 inches wide, the table below demonstrates that you need an image that is a minimum of 2400 pixels wide.
