TIPS FOR USING IMAGES IN YOUR WORK
Many images may be used for educational purposes with proper citation, but not all of them.
Before you use an image check the copyright information.
Look for information on how to cite the image.
It is your responsibility to give credit to the source.
Even if the image says that it is copyright-free you should cite your source.
When browsing for images, especially on Google Images, you may find inappropriate content. It is your responsibility to immediately log off of that page.
