Many thanks for your very rapid answer.
I am working on Windows XP 2002.
If I launch the exiv2 command by the ms-dos command execution line, it
works. If I launch it from my application in c++ (with the 'system'
command), the filename is changed as i explained before. And I am using
the executable of exiv2-0.16-win. So, i didn't compiled it.

The number 1266 in the new filename is always after the dot and before
the jpg extension. and the number (1266) is different at each execution.

Tell me if you need further information.
Sincerely,
Sylvie.
