Regardless of where your pages will be displayed, any images or media that you have not created yourself should be properly cited and attributed. If you plan to make your portfolio pages publicly available outside of KPU, extra caution should be taken to ensure that the use of any images or media is permitted on the open web.
If a full citation directly below the image on your page is not appropriate, you may provide a short attribution below the image and the full citation in a Reference list on your page. The short attribution should contain the creator or title (whichever appears in your Reference list), date, and retrieval statement. See the image below for an example. Follow the usual rules for your discipline's required citation style for your Reference page.
