Module development and code questions

hello everybody,
i am new to drupal and want to upload 7-8 images on the page with content I have downloaded the img_assist folder and upload it to module folder but not working and if u have any idea then plase tell me in details ..

As in menu_primary_local_tasks() ...can anyone give an example? Couldn't get a clear picture reading the handbook.

I use the great views module to order my stories by category (terms)
This taxonnomy (for example)

C
D
- A
- B

D don't associated any node, is a container term

If i use a view filtered by taxonomy term with term ID arguments, the display is:

A
B
C

No hierarchical distribution, only alphabetical order.

Can I display tree taxonomy with views? Not? What can I use?

Thanks and sorry for my bad English

I don't know why but certain searches on my site ( www.riflesnguns.com ) display a blank page while some searches work correctly. For instace if you go to my site and search for ar15 it will display a blank page. However, if you search for something like xm29 it will work correctly. I don't think this has anything to do with no results showing up either because if you search for asdfasdfasdf that works fine also.

Hello everyone in the Drupal community.

Hi folk,

I need to automatically disable posting comments/new nodes during specific hours everyday; i.e from 12:00 am to 5:00 am.

Any idea?
