If you want to see more pictures, just go to Library of Congress Photostream @ Flickr, type '1942' or 'Jack Delano' or 'John Vachon' or 'Office of War Information' in the search window - and here you are. And if you want to get access to the highest-resolution scans in the Library itself, on every Flickr photo page there's a link to original file (usually TIFF, ~100 Mb).
