python recursive search jpg file and print

Recursive file to find out ( 'jpg', 'gif', 'png', 'JPG', 'GIF', 'PNG') at the end of the file and print

bug encountered: a few good clip following photo files are displayed in JPG format uppercase, lowercase was only taken into account, leading to additional files to .JPG files are printed out at the end. . . Positioning cause problems for a long time   

Legacy: compressed files (RAR or zip) Write Processing 

　　Ideas: file decompression pip3 install rarfile have to be unrar.exe on the same directory of the current script
