New and old things in this package is:

+ Gender selection is now required at new user registration
+ Added images to the registration page
+ Added images to the edituser page

- Users can select wich gender they are in the edituser page.
- An image will show up under the user avatar on the userinfo page.

The core files is from PHPNuke 7.5 but I have made it so it can be integrated manual to other versions or if You have made changes to Your_Account/index.php - read the included readme.txt file.
