For Digital Commonwealth (https://digitalcommonwealth.org/), we just use the title as the alt tag on both the search results and item detail page. Search results: https://www.digitalcommonwealth.org/search?f[collection_name_ssim][]=Boston+Brewery+Posters&f[institution_name_ssim][]=Boston+Public+Library Item detail: https://www.digitalcommonwealth.org/search/commonwealth:t435gm075 I'm curious to hear whether others feel like redundancy of title or description metadata in image alt tags is a problem. What other information are people including in the alt tag? Thanks, Eben Eben English | Boston Public Library Web Services Developer 617-859-2238 | [log in to unmask]
