USFLDC Custom Image Download Service - HELP

The USF Libraries Digital Collections Custom Image Download Service interface is available via the separate USFLDC Image Viewer (CIV) and provides the ability to download a custom copy of the image currently being viewed according to several selectable options.

It is available for any record that has image content (beyond the thumbnail image), including photograph collections and e-book collections that have individual page images (in addition to the availability of a PDF).
