Copyright issues come into play when you pull an image from the Internet and publish it without the creator's or copyright holder's permission. While this may seem like a gray area, you can get into trouble with the owner of the copyright for that image if you use it without permission. That is not to say that you couldn't play with an image and add/subtract things from it, but you can't publish it as your own. Another issue to be mindful of is that use/publication of an image that clearly depicts a person without their permission can also be a violation of copyright. Please see the links below for more specific information regarding copyright and using digital images. If you are not sure whether your use is fair, be sure to get more information or email the Scholarly Commons at email@example.com to set up a consultation.
If a creator grants you permission to use his/her image, they will most likely want credit for being the creator of that image. If this is the case, you will probably want to be able to cite the creator in the proper format. Here are some resources that will help you do just that.
