Adding visual interest in the form of images is a widely-used method for attracting readers to blog articles. If you’re holding back from spicing up your blog for fear of cost or (gasp) copyright infringement, here’s some advice to get you informed and comfortable with posting images:
Get to Know the TerminologyUnless explicitly noted, any image you find on the internet could be copyrighted, which means you could be held liable for copyright infringement. Are you up for taking that chance? Those of us who prefer to stay legal will typically be looking for images with some form of a Creative Commons license. This license is less restrictive than the traditional “all rights reserved” copyright (to varying degrees). Here’s a breakdown of the terms, acronyms, and icons associated with them, according to creativecommons.org:
Attribution: CC BY
Allows you to distribute, tweak, and/or build upon the original image for personal or commercial purposes, provided that you credit the creator.
Attribution-NoDerivs: CC BY-ND
Allows you to distribute the image “unchanged and in whole” for commercial and non-commercial purposes, provided that you credit the creator.
Attribution-ShareAlike: CC BY-SA
Allows you to tweak and build upon the original image for commercial and non-commercial purposes, provided that you credit the creator. Any new art you create based on the original image will carry the same license and be available for commercial use by others.
Attribution-NonCommercial: CC BY-NC
Allows you to tweak or build upon the image non-commercial purposes, provided that you credit the creator. Any new art you create will not carry the same license as the original image, but still must be used for non-commercial purposes only.
Attribution-NonCommercial-ShareAlike: CC BY-NC-SA
Allows you to tweak and build upon the original photo for non-commercial reasons only, provided that you credit the creator.
Allows you to share the image, unchanged, for non-commercial purposes only provided that you credit the author. This is the most limited license.
Image Borrowing Best PracticesEach image released under creative commons likely has one of the above licenses or some variation of it. To be on the safe side, you should always check the license agreement to make sure you aren’t violating anything. It may take some time at first, but as you become more familiar with the licenses, you’ll know where to look to determine the facts more quickly.
Not all free images require a credit to the image creator; many images on stock photography site Stock.xchng don’t ask for attribution, but their standard license does request that you “take the time to comment on and rate the Image you downloaded and do your best to show the work you created with the Image to the photographer.” Whether you’re crediting the image author or simply letting them know how the photo was used, it really is a small price to pay for a free, quality, and legal image.
Where to Find Free, Quality ImagesSome of the best places to find free stock images:
This site describes itself as a “license-specific photo search engine.” It searches many of the popular free stock photo sources and allows you restrict results based on a variety of parameters, including account requirement, shape, resolution, and license.
2. Flickr’s Creative Commons Search
This social image-sharing site has gained a reputation for harboring high-quality free photos. Search through the Creative Commons section or use the advanced search feature to specify a search within the Creative Commons-licensed content, plus you can identify whether you’re looking for content that can be edited or used commercially.
As discussed earlier, there are plenty of images on this site with more lax licensing that doesn’t require attribution. However, you’ve got to watch out for the much higher quality, payment-requiring iStockphoto thumbnails that get posted alongside the free stock.xchng results.
If you’re just looking for something small, stock photography site 123rf offers many of its small-sized (think 400px at the longest side) images for free. Just search their free images section, found under the Stock Photography header on the home page (or by clicking their link above).
5. Google Creative Commons Image Search
Of course, if there’s a searching need, Google has a tool for it. Within their existing image search, Google added a usage rights parameter to their advanced image search. Here, you can specify whether the image should carry a license that allows reuse, commercial use, and/or modification.
