Post installation

I am trying to convert my site content to work on a nice, organized system which will prevent future hours of hand jamming html and updating links.

My biggest problem right now is that I have no knowledge of how categorizing works in this system. The user guides and documentation don't seem to give a plain english enough dummy guide to this.

To get me started can someone give me a brief dummy run-down to this
Let's say I want this Category Structure

How do people manage the images on their Drupal sites -- what are some common practices?

As I'm posting content to the pages, I am attaching images to individual nodes. As it stands, each image is associated with a specific node yet I can use that image anywhere on the site (since it gets uploaded to a central directory). What's a good way to manage all my images in a centralized manner? Any recommended modules / practices?

Let me know if I'm not clear in my question.

I have a couple of custom blocks that use php snippets to format lists of different content.

In Firefox, they look just as I would expect. Viewed through Internet Explorer, these blocks sit at the bottom of the page.

You can see the effect here.

I'm using Leaves - a phptemplate theme. If you could suggest what causes this, I'd be grateful to know.

Cheers, Rob

...because I can't find 'em. :)

I snag a ZIP Code from users when they first sign up, and its in the account's profile category edit page (user/[#]/edit/[profile category])

However, when I go into the database {profile_values} where profile data is usually stored, no entries for ZIP are stored; there's not a single row with the FID that corresponds (via {profile_fields}) with the field.

I noticed that in my web site with drupal 4.7 RC2 I don't have anymore the sections that I can hide, like it happens with the categories section in the "Submit forum topic". Does that depend from the browser? Or do I have to set something to see that?

Thanks for your kindness.

Is there a way to place an user in a definited rule? I would like to be able to create the rule "contributors" and decide who put on that rule.

Thanks for any kind help.
