"Macaulay Library" images
Description
When navigating from image to image, voice over reads the name of the image twice because the image alt tag and the highlight text have identical content.

Applicable Guidelines

Guideline Observations Recommendations Testing Actions
Guideline 58 Link destination is described by link text on its own or by link text programmatically associated with other text on the page (except where the destination is ambiguous to all users). (Fail)
2.4.4 Link Purpose (In Context)
The identical content in the image alt tag and the highlight text causes redundancy, making it unclear for users relying on assistive technologies. Ensure that the alt text for the image is unique and descriptive, or modify the link text to avoid redundancy. Test the page with a screen reader to verify that the image and link text do not announce the same content.

2.4.4 Link Purpose (In Context)
The issue arises because the alt text of the images and the associated highlight text are identical, leading to redundancy in the screen reader output. Modify either the image's alt text or the highlight text to provide distinct descriptions for better clarity. Use a screen reader to ensure that the image and the link text provide unique and descriptive information.

2.4.4 Link Purpose (In Context)
The issue arises because the image's alt text and the highlighting text are identical, causing redundancy when read by screen readers. Modify the alt text of the images to provide a unique description that conveys the image's purpose without duplicating the highlight text. Use a screen reader to navigate through the images and ensure that the alt text does not repeat the highlight text.

2.4.4 Link Purpose (In Context)
The identical content in both the alt tag and the highlight text causes redundancy when using assistive technologies. Ensure that the alt text for the images is distinct from the visible link text to avoid redundancy. For example, if the alt text describes the image, the link text should provide additional context or use different wording. Use a screen reader to navigate through the images and ensure that the same content is not announced multiple times.
Guideline 66 For user interface components with labels that include text or images of text, the accessible name contains the text that is presented visually. (Fail)
2.5.3 Label in Name
The image's accessible name is being read as the same as the visible text, creating confusion for users relying on screen readers. Modify the alt text or the visible label so they are not identical, ensuring that they convey different information. Check with a screen reader to confirm that the accessible name is not identical to the visual label.
