The Compare Tool is useful for making your final image ratings. Sometimes when an image is a MAYBE, it is because it is so similar to another image(s) that its difficult to decide. You can use the Compare Tool to see those images all together on one screen!
Once you have finished your first round of rating images, you might find that you have a handful of similar images with Yes and Maybe ratings. To make your final choices, select the Compare Tool from the bottom left menu.
The Compare Tool can also accomodate more than two images, so if you have three, or four, or even more that are similar you can view them all at once.
