Post installation

Where/how do I turn on Breadcrumbs? I get "Home" on almost all pages but nothing else.
I read several threads here on the topic but they all apear to imply that breadcrumbs work out of the box and then suggest all kinds of code modifications and or add-on modules. I tried two modules and neither added BC's tomy site. (breadcrumb_categories, taxanomy_breadcrumbs).

Hi, I am using the audio module to upload and play mp3's. sometimes it will play the file from the page that displays the content of the node using a flash button. Othertimes it will have a "Click to play" link that launches a new page and plays the file using quicktime. is this a mime type conflict, any suggestions on how to get the behaviour to be stable and always play using the flash button?

I already have all the products and the categories the products belong to.
However, when I create a new product there is no any option that allows adding the image to a product. That's why I cannot add images.
Could you tell me what do I need to install in order to be able to add a picture to a product?

I have tried the taxonomy_dhtml blocks, the taxonomy_menu...nothing looks/acts like the actual mydomain.com/taxonomy_dhtml mainpage list. I really want that tree in a block...what code would i need to insert into a custom block? TIA

For some reason my Drupal 4.7 installation has problems with modules that use drupal_get_path to figure out where they're installed. For instance, I've just installed TinyMCE, and I'm getting an error
Fatal error: Call to undefined function: _tinymce_plugins() in /srv/www/htdocs/modules/tinymce/tinymce.module on line 376

Just before that line it says:
function _tinymce_get_buttons($skip_metadata = TRUE) {
include_once(drupal_get_path('module', 'tinymce').'/plugin_reg.php');
$plugins = _tinymce_plugins();

Is there a way to turn off that article track tab? I think the one for users is useful, but I really dislike the one for the articles. Anyone know how to disable that?

thanks in advance.
