Single post in A List of Items in Tables

So I'm currently working on reordering one of the gems table (by type; favorite-least favorite). On the post here and also in the code available for use the icons for the gem types appear as a broken images (except for two), but all the gems are visible in the chart. I can fix the type icons myself for this code that I have, but I just wanted to give you a heads up for the code that is here.
