Batch Background Removal

[ct197475]

Hi Ofnots,

Thanks for your help but I feel I am far away from getting this done without your coding help.
I am unable to translate all what is obvious for you pythonwise :-)

Could you please correct this code, knowing that the purpose is to deal with 400 photos and I would like their name to be the same in another file.

PS: my business is very small so I need to use to the max GNU solutions and their generous community;

Thanks again,

Chris
