Just right click the photo you want to download, then select the ‘View Page Info’ and activate the ‘Media’ tab. The list shows all the graphics on this page. Click an entry to see the preview in the lower part of the dialog box. Keep scrolling till you find the desired image. Then click ‘Save As’ and save the image on the hard disk.
