How is Getright better? Well, it displays all the images which you can simply click to select, and then it downloads into a directory. Therefore, if you want all the images, you tell it to download all (two clicks) and click go (one more click). Otherwise, you'd have to right click -> Save Image As -> Enter filename -> Ok (3 clicks) per image (x 50 (for example)) = 150 clicks.
Also, while Getright is downloading, you can be busy browsing another site - something you can't do while you're busy right clicking, left clicking and everything else.
