Yo blag,
Glad it worked, but please don't be cryptic, if there is something wrong with my instructions I need to know it, so please do go into detail.
Also, please let the world know what you did to make your LRG images work, in my humble opinion no hack is needed, just to load your LRG images into images/large/attributes. MED was just an example, you can do same with LRG.
I don't quite get what you meant by duplicate folders, only one images folder is needed for this, with a couple subfolders that you create.
Looking forward to your reply.
