Trying to have dynamic image file path per node

Issue Summary

I've been looking for a module to view images attached or associated with a particular node. That is, we import lots of images into a folder: files/[contenttype]/[idorcckvalueofnode]/all the images

So, I was wondering whether changing the function 'couloir_slideshow_block' from
function couloir_slideshow_block($op='list', $delta=0, $edit = array())
to...
function couloir_slideshow_block($op='list', $delta=0, $edit = array(), $node)
or...
using arg(1) within the function
... might make it possible, with a couple of tweaks in the "case: view" section (building the $imagepath string) to show just images from the specific node's images folder. Is this a crazy idea?

Planning on trying it on my testing box. Then, put the block in for the content type of choice and see if it knows which images to load.

Thanks, hope it works...
