Drupal 7.x

I want to add a file browser to the Article Photo field in Drupal 7. Is this possible?

Anybody knows how to hide the form in the node preview mode?

I am looking to create a simple photo slideshow for Drupal 7. A lot of the popular slideshow modules do not have version 7 compatible releases as of yet. I am looking for functionality similar to that at the following URL: http://www.gwillikers.com/about-us/photos. Has anyone had success with implementing this kind of slideshow in Drupal 7??

Your help is very appreciated!!!

It suggests that the release date is today....

When I define a global var in my module_boot and give it a value then this wil not be available in other functions

Define in module_boot():

  global $_wmgen_users;
  $_wmgen_users->name = 'Name part';

Usage in other function eg module_user_login():

  global $_wmgen_users;
  drupal_set_message(t('Global name %name.', array('%name' => $_wmgen_users->name)));

Thx in advance for helping me out.

I installed Drupal 7 beta on my local machine using Xampp and uploaded and enabled a few modules and everything was working well.
I then followed all the documented steps about migrating the database, compressing and uploading the files to the public server but when I tried to test it in the browser I got the following error:
PDOException: SQLSTATE[28000] [1045] Access denied for user 'comRus'@'localhost' (using password: YES) in lock_may_be_available() (line 163 of /home2/bccan/public_html/bathurst-kgc/includes/lock.inc)...
