Module development and code questions

It seems that two separate tables, namely term_node and forum, both keep two columns (nid and tid) defining bindings between nodes and specific taxonomy terms with which they are associated. Is there a reason for such duplication of data?

Drupal 4.5.x.

I am writing a node module in which not everyone will have read access to all nodes. This I have implemented with the _access hook for argument 'view', and it works well.

The problem is the front page. The node_page_default() routine does check node access using the new node access API, but does not use the _access hook. This means that new nodes will be published on the front page, and a user can read the 'teaser', but if he clicks on the node, he can not read the 'body'. This is a bit weird.

I have no idea what is wrong. I installed the module, per the doc, and then tried to upload an image. I get the "Your image was created" message, but what I see where the image should be is the dreaded box with a red "x" in it. Looking at the box properties, I see the path for the image. Checking via ftp, I see that the image is indeed at that path. So, why doesn't it show up? Is it a permission thing? I CHMODed everything in the image paths to 777 and still no luck.

Hi, I am trying to change the HTML produced by the webform.module

So far, I want to avoid tables and use divs and spans... I tried to change the code in misc/html.inc, but other that nothing happens. It still show the form using the table. Even by re-posting the form I have the same problem

I changed the code on this way:

I'm struggling to load new content into Drupal, and have two problems I would like to try to resolve:

When I try to submit an image, it's saying:

The uploaded image(1280x960) is too large (max 1024x768).

How do I change this to accept larger images?
