"Image link contains both alt text and surrounding link text"

[phette23]

Sa11y error:

Image link contains both alt text and surrounding link text. If this image is decorative and is being used as a functional link to another page, consider marking the image as decorative or null - the surrounding link text should suffice.

This occurs in sidebar images, LinkedImage blocks, and ProductGrid blocks wherever I wrap a link around an image with alt text and also some label text. See errors on the Library Data page, for instance. The solution is to not include the alt text at all and mark the images as decorative by setting alt="".
