Documents, Images, Video
Documents
- Use PDFs sparingly. To the extent possible, provide content as HTML (by creating a web page).
- When it becomes necessary to link a document file (e.g., PDF), make sure it’s accessible.
- PDF, Word, PowerPoint, and Excel provide basic accessibility features.
- Learn how to create and verify PDF accessibility with Acrobat Pro.
- Using Adobe Acrobat X to create accessible PDF files from Microsoft Word.
- If document content cannot be made fully accessible, provide an accessible alternative.
Images
There are several websites that provide access to copyright-free, usable images that you can include in your website. Some also have stock video that you can use for your projects.
Here are a few of the most popular ones:
- Unsplash
- Pexels
- Vecteezy
- Pixabay
- Adobe stock photos: ETS procures a limited amount of free stock photos per year. Contact your IT coordinator for details.
Please note that these sites may also include images that require a license or purchase, so be sure to select just those images that have free use rights.
Content images should be RGB or Index color format. Generally, size images at a resolution of 72 ppi (pixels per inch) with dimensions no wider than the maximum width of the space in which it will be displayed.
Save images as JPG file type; except when Index color or transparency is needed, in which case save as PNG or GIF file type.
For non-text content to be accessible, be sure to provide alternative (alt) text. For details, read WebAIM alt text guidelines.
Video
- DO NOT UPLOAD VIDEO files directly to WordPress. Use a video hosting service such as Vimeo or YouTube then add the embed code to your page or post.
- To be accessible, multimedia must provide synchronized alternatives (e.g., captions and/or transcripts).
- Read WCAG 2.0 guidelines for time based media.
