Very nice plugin, so far everything has been working well for me except one issue - when I upload my images to my product listings, the thumbnail previews don't load and show a broken image. The images are saved and loading find on my site though. I couldn't find anything specifically in here on how to fix it but I think I read it has to do with my config file? Any ideas on how to get this working because it would make things 10x easier if I could see the thumbnails for my products.
