After you search for images of interest and add them to your cart, you can download them.

The most convenient method of downloading them is by using the NBIA Data Retriever. You must install the NBIA Data Retriever before you begin downloading. You only have to install it once to use it in future downloading sessions.

If you are using Linux, you can access NBIA Data Retriever's command-line interface, which does not require the desktop environment.

Consult the NBIA Data Retriever FAQ for more information about NBIA Data Retriever versions and usage.
