Hi,
I tried the new 2.x version and got the same problem as reported here: http://drupal.org/node/207557
When I tried to dowgrade to 1.6 version I got these problems on all my nodes:

I check the image tables and the image files. They are there. I don't understand what happens exactly.
Thank you for your help.

I don't think downgrading is generally possible with Drupal. To downgrade, you'll probably need to restore a database backup you made before attempting to upgrade, and you'll probably also need at least a backup of your files directory from before the upgrade.
