O que devo fazer para verificar se a mesma imagem está presente em qualquer outra subpasta?

It’s written mostly in Python 3 and has the peculiarity of using multiple GUI toolkits, all using the same core Python code. On OS X, the UI layer is written in Objective-C and uses Cocoa. On Linux 7 Windows, it’s written in Python and uses Qt5.
