To enhance the slides in your presentation, you can find images that relate to your topic and add them to appropriate slides. One of the best places to go for this is Google Image Search.
Write down which website the image came from because you will need to include a citation for your image on your works cited page and this will also be used for the credit line under the image.

In addition to including a citation for your images on your works cited page, it is good practice to also include a credit line under the image on your presentation. This lets your audience know where you obtained the image. Below you will see an example of a credit line.
