The whitelist currently includes link.nypl.org which is where TIFFs are available for download, however at images.nypl.org the archives have highly useful full size jpeg transcoded versions which are also cropped, so that scans including colour markers/rulers are trimmed down to just the scanned artefact or page. These are perfect for Commons, especially whilst TIFFs do not render as well into thumbnails for Wikipedia articles.
