Alt text

The theme uses two images in the footer to "cap" the ends of the links there. This is fine, but the images currently have alt text of "img", which could be improved. Using an alt of "img" alerts screen reader users to the fact that the image is present, but doesn't provide any useful information about what the image is there for.

Since the images in this case are purely decorative, and don't add anything to the intellectual content of the page, they should be done as null alt text instead. Just delete the "img" part but keep the alt attribute in the tag. Having an empty alt attribute makes most screen readers simply ignore the image, which is perfect in this case since blind users don't really need to know that they're present at all.
