This is used to add labels to the Images. This Image viewer can display the image by the order of the number in the images' name.(The Images have already named in order of numbers from zero to n.) And then we write down the corresponding class of the image which is displayed in the tool. Finally,save the one line text file as the label.Load the text file in python as an List. Then read the Index of the number in the list,the index should equal to name of the corresponding image.
