Module development and code questions

When I navigate to settings >> image I can't see any way to choose between imagemagick and GD2. My hosting provider says the GD2 library is enabled. But I cannot switch to it through my admin panel, looks like imagemagick is my default toolkit or something... any ideas?

I need to tell my filter not to process on pages that are not being displayed as the whole page (that is, not on teasers and not on search results). From this page I would have though $page would do it, but it's coming back as null when I display it with dvm($page). $teaser doesn't work on search results page it seems and I don't want to force people to use a function to display search results as true teasers to use the filter.

I've just recently started using Drupal and added the combination TinyMCE + IMCE to my installation.
The modules seem to have been installed fine and they appear when I start to edit text content, I also manage to upload images to the server. BUT I can NOT add uploaded files/images to the content. In the IMCE “Image/File Brower” I have no ‘add link’ I ONLY have a ‘delete link’ in the ‘operations’ field.

Hi everybody. I am trying to submit data from a select list without hitting a submit button (just by changing the select list value).
How do I go about that?

I'm looking for a way to set node permissions based on the relationship with the node author. Since I'm running a Drupal intranet site, I often have to route forms between staff based on the relationship between the staff; employee >> supervisor. It's easy to set up roles based on these generic classifications, but if I want only one supervisor of a particular employee to see a node this employee created, I can't think of a way to do this?

Does anyone have an idea? Could views and arguments be the answer?

Hi,

I want to display a form with a pick list with for example user names that when a user name is picked and submitted returns not the user name but the user id. And of course I don't want to display the user ids.

Here's an example of how to create a pick list (with pseudo code for inserting user names, users was just an example). Could anyone please tell me what to change so I can catch a hidden value (id) of the row (e.g. user name)?

$options = array();
while more users {
$options[] = a username;
}
