Stock photo and image sites like Shutterstock and iStockPhoto host large inventories of royalty-free images, including images of numbers and years on the Gregorian Calendar. Registered members can download images or print them out for a small fee.
Shutterstock has a searchable database of photos and images that can be used in graphic design or for other purposes. It contains many images of numbers and dates in different fonts and styles, with and without backgrounds. Shutterstock has multiple subscription plans to fit the members' budget needs.
iStockPhoto has a search filter that allows users to look only for what they want. Search terms can exclude unrelated images and help to narrow down results. Registered members can pay for images through purchased credits.
