If you’d like to use digital images found online to enrich your tutorial sessions, the two golden rules are:
• do not use Google Images – use safe sites instead (see bottom of page)
• always credit the source
That is because the vast majority of images on Google Images are someone else’s copyright. That means that even though they’re viewable online, the public do not have the right to freely use them. Furthermore, if there are people in the picture, there’s the added issue of not knowing if the pictured people have given their consent for their image to be freely used by the public. It would be a lengthy process to locate the copyright owners, and all people pictured, and ask their permission. In order to avoid all this trouble, please only search for images on websites which contain Creative Commons images. That means that the copyright owners of the images have given their consent, thus everyone can use them for free and without need to ask permission.
