The images links included on the Database search with arrangement page do not have accessible names.
The alt attribute for a functional image, such as an image link, will be used to create the accessible name for the link. Screen readers have tools to collate links into a traversable list and someone using one will often use this feature to quickly find links they are interested in. When alternative text is repeated on the page it is confusing for them. Refer to this W3C tutorial article for more information about functional images, "W3C Tutorials -> Images -> Functional images" - https://www.w3.org/WAI/tutorials/images/functional/
In this instance the image links are duplicates of the search results headings and are unnecessary. Recommend removing the links and providing alt text for the images ore marking them as decorative. Suggest:
//notice the alt text has been set to null (""). The original alt text was duplicating the heading text. Also notice that aria-hidden="true" has been removed from the images, alt="" provides the same result.
