Re: [Matplotlib-users] Trouble with api example code within watermark_image.py

[Thore O. <tho...@is...>]

Dear Thomas.

Thanks again for your reply.
I have tried your solution of putting the logo-file into
the folder %HOME% on my Windows system. Actually what happened
is that after invocation of the script the file vanished into the nowhere...
I couldn't see any change in the error output otherwise I would post it 
here.

Kindly regards,
Thore

PS: Thanks for your hint regarding the multiple post. It was
a stupid mistake and I promise it will never happen again. Sorry again 
to all annoyed readers.
