I'm not an expert but have had similar problems. Since longer entries (01_IMG_001.JPG) don't work and shorter ones (001) do, I'd try
putting the 2 barcodes one over the other and make them longer. You may just be trying to fit too much data into too short a space. As far as I understand, if you have 9 char/in and a 14 character entry, you need a barcode nearly 2 in long.
(BTW, I like that Sansa is a subject but I would have used Arya, or Danny Targaryen)
