Module development and code questions

Hi, working on upgrading a gallery2 mod. Was wondering if there was a hook to catch it when roles are added or removed. I want to map roles to g2 groups, but I think I need this ability to do it correctly.

Hi All,

Hello everybody

I have modified the block.module to include role specific visibility setting for blocks. With this you can configure the visibility settings for blocks based on roles. Please tel me if anybody needs it i shall send the code for the same.

But i want radio buttons to select 1 option from multiple options.
This can be done with list selection, but i prefer radio buttons.

I have a program that is not a drupal module, but I want to control access to it through drupal navigation menu. I am on drupal 4.7 and tried adding the program as a menu item, but I get a blank screen. So now I am thinking I should open the program in a new browser window. How should I do this? I looked at the chatbox module which I think opens a browser window, but I don't understand the code. Here is the code from chatbox that I think is how it launches a browser window.

Hello! I have a problem with taxonomy_image module, I've installed this module and I've activated from Administer->Modules and configurated from Administer->Settings->Taxonomy_image correctly.
