Module development and code questions

Hi guys and thanks for your time. I've been toying around with Drupal, actually I've moved from PHP-Nuke. At anyrate, to get to the point, I'm trying to put up a literature site. Without book reviews a literature site wouldn't be the same. I have article, blog, collaborative book ect. but they all don't allow users or me the admin for that matter to upload an image to pair with the story.

I've made a few simple changes to the image.module code for my own site, and I'm curious if they'd be of interest to other people. In short, they relate to making standardized 'node display' versions of images, and specifying dimensions for resizing.

Hi all.

Pleas help my find were is my bug in code or how I register thet item as the childe.

Here is my source code part of module_link() hook:

I need to pass a variable from a module I'm writting into a theme's function header(), what is the best way to do this?

At the moment I'm using $GLOBALS["variable_foo"], is there a better way?

To tell you the truth, I've got a phpBB forum already running. Has there been any efforts in trying to combine the two systems?

I needed an alphabetical browser of all published nodes, and couldn't figure out how to do it using existing Drupal tools, so created one in Dreamweaver and made a static page out of it. Maybe someone can make a module out of it? It needs at least four big improvements that I can think of -
