Each of these files is about a hundred KBytes in size. When you left click on a link, that file will be downloaded to your browser. If you want to save it at that point, right click anywhere on the picture and select the save option, specifying where you want to save. Alternatively, you can right click on the link before download, and choose to save directly to a file. Browsers differ, so play with it. Email me if something isn't working.
