Every business needs images on its website, social media profiles, and marketing materials. But if you\u2019ve found an image online, it could be copyrighted. And using copyrighted imagery without permission is illegal.\nWhat is copyright exactly, though? And how can you find free images to use (legally) for commercial reasons? Here\u2019s a rundown of what you should know.\n\nWhat Is Copyright?\nAs a concept, copyright is quite straightforward: it protects authorship of a creative work. If you create an image, you are the 'copyright holder'. And this means you have the right to use it however and wherever you like.\n\n\n[caption id="attachment_11312" align="alignright" width="269"] The famous 'copyright' symbol.[\/caption]\nWhen using an image you've found online, though, someone else may own the copyright. And if you use an image without permission from its owner, you could be accused of copyright infringement.\nThis is crucial to remember because, if you're found guilty of infringement, you\u2019ll be liable for damages. So while using an image without permission might not seem like a big deal, it could cost your company a lot of money. And because copyright is so important, we have two key rules:\n\n\n \tAssume images online are copyrighted unless you know otherwise.\n \tNever use a copyright image unless you have permission.\n\nThere are free images available for commercial use, though. You just need to know the kinds of images you can use for free and where to look.\n\nPublic Domain vs. Creative Commons Images\nThe two main image types to look for are Creative Commons (CC) and public domain images. Both can be a great resource, but each has its own rules:\n\n\n \tPublic domain images are copyright free, so you can use and modify them however you like without paying anything. There are still some rules about using these images (e.g. if it is a photo of a famous person, you might want to read up on model release rights), but generally they are safe.\n \tCreative Commons images are copyrighted works where the creator has given certain rights to people who wish to use them. There are several different CC licences, each with different permissions attached (e.g. many CC images are free to use as long as you credit the creator). If you are using a CC image, make sure to check the licence type.\n\n[caption id="attachment_11319" align="aligncenter" width="408"] Creative Commons licences.[\/caption]\nBut where can you find these free images? We have a few suggestions\u2026\n\nWhere to Find Free Images\nThere are many sources for finding free images you can use legally, including:\n\n\n \tGoogle Image Search \u2013 The first stop for most people looking for images. Not every image on the Google results page is free to use, though, so you\u2019ll need to set the usage rights filter to Creative Commons licenses.\n \tPixabay \u2013 A database of public domain images, most of which are free for commercial use. Similar sites include Pexels and Unsplash.\n \tCC Search \u2013 CC search is a search engine dedicated to Creative Commons content, including images and videos. You can use these images according to the permissions specified under their licences.\n \tFlickr \u2013 A popular image hosting website. Most images on Flickr are \u2018All Rights Reserved\u2019, which means you have to seek permission from the creator(s) to use them. However, the \u2018Advanced Search\u2019 option on Flickr allows you to look for images with a Creative Commons licence.\n\nAnd if you have copy that you're using alongside your images, having it proofread by an expert will ensure it always has the right impact.
