Module development and code questions

I need any to know if there is any module that works like Mambot in Mambo term. What do I need is add a text (from a field) before page on certain node displayed. I know that we can use hook_init() but I need more doc for this function, or better any sample module that works like that.

Thank You.

Does anyone have both the filemanager and taxonomy_theme enabled and functioning together?

taxonomy_theme seems to be just completely removed from the module list when i have filemanager enabled.

if i get rid of filemanager, taxonomy_theme comes back just fine. i really need to use taxonomy_theme along with acidfree (which required filemanager).

any ideas?

What's the method for clearing session variable values when the browser is closed?

I set session.cache_expire to 0 in settings.php, but it didn't make a difference.

Note: I'm asking about clearing session variables, not cookies.

Thanks in advance.

The multipage form example on drupal.org is for node type. I do not know how to control it to really submit it in certain step. It seems that node type can decide which step is the real submit. But how can I do it in my module?

In my module I have a form for user to upload some files. I can add the element of 'file' type to the form. But how to do the upload after submit? Can I use upload module here?

hi,

I require to make a thumbnail image of every user profile picture, when he uploads an image as his profile picture. Where do I add the code so that, a thumbnail is also created and saved, along with the original image when the profile image is uploaded to the specified folder.

Where is the code section to save the uploaded profile image to the folder. Is it within the user.module?

thanks
