Module development and code questions

Hi, I am a new Drupal user, however I am absolutely loving it! This has got to be one of the easiest to use and most versatile software out there.
I am just wondering, are there any modules out there that would allow others to add an image to one of my posts. For example, I post a story and I upload a few pictures with it. Are there any modules that would allow another user to add a few more pictures to that particular story?

I think I posted in the wrong area (http://drupal.org/node/76094)

Just looking for some help on saving misc items to a transaction, can anyone steer me in the right direction?

I've got a crisis with subscription billing. I'm not great with e-commerce in general or the e-commerce modules. We want to have some paid advertising on our site including paid directory listings, banners, featured placement, coupons, etc. where essentially they submit content and it's visible as long as they maintain a subscription.

I've got a tree structure that comes from taxonomy_get_tree() and I want to theme it as a nested list. Is there a way to do it with the actual tree data structure I get from that function or is there yet another way via the $vid var?

I'm trying to create a module that will add functionality to all blocks. I can use hook_nodeapi() to insert content into my node body, but I can't figure out how to do this for blocks.

Hello,

I'm using the modules i18n and path.

I need a short PHP code that retrieves a node's title (or the nid) having a path as its input.

Somethink like this path_to_title('en-us/about') or path_to_title('about')

Regards,
