Every small business needs professional photos from time to time, whether they're for marketing materials, business projects, or a website. Hiring a photographer or using a traditional stock photo house can be pricey.

FreeDigitalPhotos.net has thousands of images available for free download and limited use. Some resolutions may be too low for your particular use, but higher-resolution photos are also available for purchase. Just make sure you reference the photographer and FreeDigitalPhotos.net anywhere you use the photo -- and check the site's terms of use for any other restrictions.
