How can I download an image or other item?

To download the highest quality jp2 or TIFF image

A “Save as” window will open. Choose the file destination and then click “Save.” The image will be saved onto your device, with a filename that matches its local i.d. number in digitalsf.org. You can use that local i.d. number to cite or retrieve the item in digitalsf.org later.

Please note: jp2 images will not open in your browser. On a Mac, jp2 files will open in Preview. To open jp2 files on a PC, you need Photoshop or other image editing software capable of handling this file type. On a web browser, search for “opening jp2 files on a PC” to find free software applications you can use.

2. To download a lower-res image that you can view with a browser, use the download button inside the viewer. Choose the last option down:

Select “Save as,” and use the Local Identifier (highlighted below) as your filename, e.g. AAP-0013. This will be useful later when you’re citing or trying to retrieve the image again later:

For download options, what is the difference between current view and whole image?

“Current view” will save just the portion of the image that is displayed in the viewer in a new tab, whereas “Whole image” will open the entire image in a new tab.

What is the difference between a TIFF, jpeg and jp2?

TIFFs are lossless files that contain all the original file information without degrading the quality of the image. TIFFs are large files and are great for long-term preservation or editing. Jpgs are highly compressed files that are good for online publication and sharing due to their relatively small size. The type of file compression used in jpgs does cause some loss of detail in files, though not always viewable to the human eye. Jp2s are high-quality files with a large amount of compression, allowing them to be much smaller in size than TIFFs. Please see the “how to download” instructions for information on how to open jp2 files on a PC.
