Sorry for jumping into this conversation. In my opinion the problem I see is the need to have a folder for each game, I think the best aproach would be to have one folder where we can drop all the images, including a default one that could be named _default.jpg or something like that. That way we could just drop all the images,and even if the game was never launched before the image would be picked up. I use different methods for renamlng images, videos and docs in in bulk, and I prefer that to having to drag and drop files individually to folders.
