Using Images Appropriately
One of the biggest problems we have using the Internet is the "borrowing" of images. All images on the Internet (just like the words) are owned by someone, so you can't just take them and use them without permission. Below are some links to places that you can go to get images whose owners have provided permission. Some will ask you to pay for the use of the image, but some are free. You will still need to give attribution for them, but at least you will know who owns the rights to them!
Pics4Learning provides copyright free images for students to use in their projects. They also provide a proper citation for you to copy and paste to give credit.
