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).

Note: for screen, medium, and large resolution the image is normalization to the equivalent of a 8"x10" print size during scaling because the source materials are of a great variety of physical sizes, digitized with a variety of equipment with different capabilities.

PNG. Medium to low compression.
TIFF. Un-compressed. Display in browser requires plug-in, otherwise save directly to your computer.
Depending upon your browser configuration, when the Download button is clicked the JPEG and PNG images will open in a new tab/window. The TIFF image will open according to the browser plug-in (or a browser dialog box will open requesting your input).
Saving the file
With JPEG and PNG, in most browsers you can right-click on the image and select the Save As option.
With TIFF, if available, use the save/save as option offered by the browser and/or browser plug-in.
Note: Downloadable images are generated on the fly according to the request parameters from the available JPEG 2000 image.
