Got instructions from PS on standard sizes to use for images of
artefacts in archive:
thumbnails 100x100 (crop and resize), 500px wide to fit in content box, 1024px wide to fill page width, original
page images
thumbnails 100x133 (compromise aspect ratio), original, (maybe an intermediate size as well)
set up folder structure with copies of images for Gord and Malcolm to go through and process the files
