Content Style Guide: Images, Video, Audio
Use graphics in moderation.
Images can be an effective way to engage users, inform, and illustrate concepts but with all things, should be used strategically.
- Don’t use an image if the subject of the image is just text (for example, don’t use an image that says “About Us” because you want a special font).
- Don’t use animated graphics (unless the graphic is still by default and the motion can be triggered by the user).
- Use purely decorative images sparingly.
- Avoid clipart and generic stock photographs.
Use appropriate image alt text.
- 125 characters or fewer.
- alt text should describe the image for users who cannot see it.
- Follow WebAIM guidelines for image alt text.
Use only images we have the right to use.
- Ideally, the image would have a creative commons license.
- Give attribution to the creator by adding text under the image in LibGuides.
- If creative commons, make sure you follow what the image’s license dictates.
- Add a caption to display copyright.
Load images over HTTPS
- All of our services load over HTTPS, so all content that we use on our pages also much load over HTTPS. Make sure the URLs of your images, video, and audio begin with https://. Have questions? Drop me a line.
Video and audio should provide text-based alternatives.
- Videos should include captions.
- Audio files should include transcripts or text equivalent.
