Module development and code questions

I've recently setup the lightbox2 module and it's really great for fixed width sites. There have been a few issues with the image module integration, ones that I cannot alter; however, if they were improved, it would be a great contribution to the module.

Hi,

I have installed drupal on my main site (http://otg.com),and i have registered my first user as admin(by default they have admin role).Then i have created two users (say test1,test2).What i wanted to do is to diffrentiate the content for diffrenet users.

For example if i logged in as "test1" my theme,content,posts,blogs should be kept as private and when i logged in as "test2" i cannot see the postings ,themes ,contents of "test1" and "test2" have thier own contents.

Hello,

For a site on which I am working I require a full-featured image gallery. The Shazam Gallery module seems to fit the bill in terms of functionality, but I have some questions about permissions. Basically, I want it so that a user can view an image in a gallery if and only if they can view the gallery itself. What is the best way to do this? I'd prefer not having to alter image.module's hook_access, as this reduces maintainability.

Hi,
I had made the user profile accessible to authenticated users, other than the administrator, by changing the access control in the admministrator settings.

Where is the change brought about when I select the option to allow authenticated or anonymous users to access a module. Is the change made in the database or in any .inc file?

I may be being a bit thick here, but how do I use "hook_link_alter"?

I've looked at the API reference but don't seem to have clicked how it works....
Anybody got a working example?
Any tips would be helpful:)

Hi,
total newbie. Running first drupal site. learning lots, enjoying it...mostly. I have a snippet on the front page that I only want to display when the user is on the front page (ie. first load of site, or click on 'home'). How do i do that?

Is there an ishome() kind of function?
Cheers,
Dan
