Post installation

I've recently removed a number of aggregator2 feeds and feed items from our site. All the associated items were removed, but empty nodes still remains, whether Im looking at the front page, or specific taxonomy terms.

I have the dba module installed, so I can view our database easily. Is there a way to quickly identify these lonely empty nodes and remove them all?

Our site has about 600 aggregator2 items, so going through manually is a little tough.

Thanks for the help,

i tried to dabble with the following code :

I am confused by images within Drupal.

Is there to be a core image type (I see reference in core modules to images) ?

I know there are current DB incompatibilties with 4.7 and image.module, has acidfree suffered a similar problem, or does it work differently ?

I hate having to choose, I want to be able to create my own custom types in the near future, which will rely on an image type, question is which one, are acidfree and image.module got compatibile image types ?

I'd like to exclude authenticated users from using the img_assist feature in the forums.

The administrator should still be able to use it. It appears I can't assign roles to this module.

I was wondering about how to get the background image in any Drupal site to not change it's position as you scroll down the page.

Thanks on forehand !
