thx for your answer
you right, i'm on Windows
i'm agree with you, my code is ugly with file path, it's just a crash code
simplification for my post
the problem is with os.remove on original image
if i launch my script in interactive mode, without the last two lines (
os.remove and os.rename)
python -i compress_dwaa.py
so my python interprete still alive
i can't delete by hand my file because : "file is open by python.exe
process"
