Video Callouts

You will need to offer alt text for your video thumbnail because it functions as a link, and every link must have accessible text.

Adding & Replacing Alt Text

Consider alt text every time you add a new thumbnail or replace an existing image.

  1. Select your thumbnail image, then click the Image icon to get to the Insert/Edit options.
    • The top display of edit options for an OU Campus page. A button with a folder icon is followed by four tab options, Preview, Edit, Properties, and Versions. To the right are the Save button, a yellow lightbulb icon indicating checked out content, a green Publish button with a dropdown arrow, an Expand icon, and an ellipsis for more settings. The first row of icons includes Save, cancel, scissors, two stacked papers, a clipboard with an empty paper, a clipboard with filled paper, binoculars, undo and redo errors, spell check, italics, bold, bullets, numbered list, increase and decrease indent, quotation marks, x squared, x with a subscript, left align, center, right align, full width text, link, envelope, and anchor. The second row includes Paragraph and a dropdown, Styles and a dropdown, and an image icon in a garnet rectangle for emphasis followed by a dash, an arrow pointing left, C in a circle, a puzzle piece, two arrows in an oval, Insert component symbol, table with a dropdown, and four arrows pointing outwards to maximize content. The head on the page being edited includes the UofSC monogram, South Carolina, and Digital Accessibility.
       
  2. Make sure that the "Image is decorative" option box is left unchecked. These images cannot be decorative because they are links.

  3. Add your alt text to the "Alternative description" box. Click "Save" to confirm.
    • The Insert/Edit Image dialogue box over a callout grid. The modal includes two tabs, General and Advanced. On the General tab, Source and its text field, an unchecked Image is decorative box, and Alternate description with text field that says Description required are surrounded by a garnet rectangle for emphasis. The remaining fields are empty and include Image title, Width and Height with ratio lock icon, Class (not set), Custom Class, and ID. Cancel and Save buttons are at the bottom.

Captions & Alt Text

Most of the time, alt text and captions serve very different purposes. However, if your caption conveys all of the visual information found in your image, you can mark the image as decorative to keep a screen reader from reading the same description twice.

Challenge the conventional. Create the exceptional. No Limits.
