I'm sure the pictures are real, but they are no more representative of central Paris than South Bronx pictures would be of New York City.

I was there on business in the 80's and it was gorgeous.
I took my wife back two years ago and it looked like a third world city by comparison.
Trash, bare dirt where grass had grown around the Eiffel Tower, African/Muslim street vendors everywhere, crime rampant - disgusting.
The more rural parts were nice but Marseilles was scary even in the day time.
No offense but my impression differed from yours.
