PowerPoint users have long sought the use of search engines such as Google to find and download images to use in presentations. These images are often of variable quality. The low resolution images tend to become pixelated if scaled up and lose clarity when projected during presentations.
If you are working on a PowerPoint presentation that requires visuals to support the content, then the proper use of Google Image Search can yield high quality images. These however can be under varying copyright laws and regulations, so you will have to ensure that the image you end up choosing is free to use and share in the public domain and royalty-free.
To find high quality images using Google Search, go to the Google Image Search page and type the name or kind of image you want. For example, if you are making a PowerPoint presentation on the history of actuarial science and need a picture of Edmund Halley who was the first to demonstrate the use of a life table to calculate insurance premiums, then type Edmond Halley into the search field.

Save the image from the linked page. You can then insert it in your PowerPoint presentation on the history of actuarial science:
