Module development and code questions

OK so the page is here http://happydyke.com/image

For some reason, the first gallery has a huge section while the following two galleries are pretty much the correct size, or what I consider to be the correct size. How can I scrunch up the family gallery to look more like the landscape and pets galleries?

Hi, is there any javascript module that makes Navigation or other sidebar menu more dynamic

I would like to display a block (in this case "similar entries") inside the contemplate body. Is php to do this or a relevant forum topic to look at?

Hello,

I'm trying to overwrite the upload.module default form settings in a custom content type module. I don't want the 'attachments fieldset' to be collapsed when creating a new node of my content type.

So I have:

function mynode_form_alter( $form_id, &$form) {

        $form['attachments']['#collapsed'] = FALSE;
        $form['attachments']['#collapsible'] = FALSE;
      
}

Offcourse there should be some more form_id and type checking but I'll add these later.

Is it possible to add an H3 headline before something such as a group of CCK fields and to add a divider line with CSS to the bottom of the group of fields? I am fairly new to Drupal, so any help would be appreciated.

Heres a link to a screenshot for reference. http://img72.imageshack.us/img72/6469/screenshot002pz3.png

I have added some code to the user_access function that queries the database. This additional functionality is provided in a function that essentially replaces $user->roles with a function that returns roles based upon group context.

When someone creates a new node, say create->page, what functions are used to check create permissions?

I know user_access is checked, and I'm returning the correct values. But, what else is checked? Thanks.
