Finding Images - Best Places to Look
Image Search Engines
Google Images is a quick and easy way to find lots of images from web pages across the globe. But it only searches web content that it can find -- many images are actually hidden in databases or archives (whether freely available or in Cal Poly's subscription databases). The quality of images - size, resolution, description, usage rights - also varies considerably on the open web. Use Google, but don't rely on it for all image searches. Explore this page for more high-quality options.
Creative Commons is a nonprofit organization that develops, supports, and stewards legal and technical infrastructure that maximizes digital creativity, sharing, and innovation. You can also find CC searches in Google Images (under the gear icon in Advanced Search) and other sites like Flickr
Flickr is a public photo-sharing site with billions of images. It is a rich resource to find images for your research (news events, places, people, etc.). Flickr users can opt to share their images with others under creative commons licenses (alternative to copyright).
ARTstor is a searchable database of digital images and associated catalog data, including locally-added Cal Poly images visible through the addition of the Shared Shelf Institutional Collections feature. ARTstor and Shared Shelf accommodate images from all time periods, cultures, and disciplines.
Statista is a statistics portal which provides direct access to quantitative data on media, business, finance, politics, and a wide variety of other areas of interest or markets. The database features unlimited downloads, source citations and direct use or export of results in PowerPoint, Excel PDF and Graphic (PNG) formats.

Digital Image Collections
The University of California's free public gateway to a world of primary sources. More than 200,000 digitized items — including photographs, documents, newspaper pages, political cartoons, works of art, diaries, transcribed oral histories, advertising, and other unique cultural artifacts — reveal the diverse history and culture of California and its role in national and world history.
From the University of Washington Libraries, The Cities and Buildings Database is a collection of digitized images of buildings and cities drawn from across time and throughout the world, available to students, researchers and educators on the web.
This repository of digital images documenting the National Gallery of Art collections allows users to search, browse, share, and download images believed to be in the public domain. More than 20,000 open access digital images up to 3000 pixels each are available free of charge for download and use.
Provides free and open access to over 800,000 images digitized from the The New York Public Library's vast collections, including illuminated manuscripts, historical maps, vintage posters, rare prints, photographs and more.
Save and arrange images and media to an online, sharable workspace.
Citing Images - The Basics
Giving proper credit for images has two parts: a caption with the image itself, and an entry in your bibliography/ cited references list. Where the image appears, write a descriptive caption indicating the source of the image. Then create an entry in your bibliography.
While most citation styles do not give a rigid format for citing images, you can construct informative citations based on some or all of the following elements:
Artist's name (if known)
Title of the image (if known; if not, create a description & place in square brackets)
Institution where the photograph or original artwork is held (if applicable)
If taken from a book or journal: all the usual citation information – refer to the appropriate style guide
If taken from an online database: aatabase name, date of access, URL (if applicable)
If taken from the Internet: title of website (if it has no title, create a descriptive one and place in square brackets), date of access, URL
Concentrate on creating the best citation you can given the information you can locate. The intent is not to frustrate you with intricate rules, but to give you guidelines so that you can provide your reader with enough information that they can track down the original image if they so choose.
The guidelines offered here should be taken as suggestions, not as legal statements.
Copyright and Fair Use
The re-use of images for educational purposes (not including print or electronic publication of any kind) is generally considered acceptable under the terms of fair use. If you wish to publish images online or in print, even if for educational purposes, you will first need to determine whether or not the image is protected by copyright, then find out how to get copyright clearance.
Password-controlled web sites with access limited to the Cal Poly community generally fall within the bounds of educational fair use.
You may also need to obtain permission to publish from the institution that owns the image in question, whether or not the image is in the public domain. This is particularly the case for images found in licensed databases, such as ARTstor. ARTstor has a very clearly-worded permissions statement, as do other licensed databases. In most cases, you will need to write to the institution that owns the physical image (that ARTstor, for instance, includes) and request permission to publish it. There is often a fee associated with acquiring permission to publish.
