Making small progress.
First of all, the module doesn't find the js files. This is easy to correct by inserting the site URL before the moddir variables in admin/index.php on lines 814, 815, 820, 838, 839, and 840.
Unfortunately, after that I'm stuck again as it seems the 'spath' is undefined, thus the function to create the thumbnails can't find the directory in question and no collections are added.
So, still unsolved (the prefix for this thread should be changed), but I'm keeping my fingers crossed that Optikool or some other creative user comes up with a solution.
