I have a lot of movie files in folders named after the movie inside them. For example, a folder named 'Invictus' would contain:
folder.jpg (a small jpg image that shows up in icon view)
Invictus.iso (The actual movie file)
TViX.jpg (a large 1280x720 jpg that is displayed in icon view when you open the folder)
I would like to make a copy of each original TViX.jpg in the folders and add a renamed version with the <foldername>-fanart.jpg but most important - still retain the original with it's existing name (TViX.jpg. This would allow the original fanart (TViX.jpg) to be visible in my old TVIX m6500 and my new HTPC running XBMC. Thus adding to the existing files :
