BEWEIS 0.1 worked as described. In 0.2 I get the error "An exception of class NilObjectException was not handled. The application must shut down" after pasting a valid URL, pressing start and selecting a valid empty folder. (Version 0.2)
WOLF1X2 now i know!
i guess you pasted a valid url and clicking the make qt button to get the exeption.
the make qt button is for postprocessing (step 6) a folder full of images - not an empty. (Version 0.2)
