The links are only available if you have selected
Edit a gallery and find the Gallery Options at the bottom. Select a Download folder which is the source of the download files.
New options will appear to allow you to choose to enable entire gallery downloads or only individual images.
This feature creates a zip file of all the download files on your server, makes it available to download for the user then removes the file. However, some shared servers may not be able to handle the resources required to zip many, large files together and this feature could fail for you.
