Do you think it will be confusing for new users to have "wall_GreyStone.png" and "wall_GreyStone_thumb.png" in their Resources directory? I can try to explain somewhere, file manifest perhaps, what the files do.
I think that you might need to include some kind of file (readme?) that explains the directory structure and what files should go where. This suggestion is supposed to be for the people who aren't regulars here at this forum.
ok, exactly what I meant was this: since you have the greystone.png and greystone_thumb.png, that would have a summary/explanation in a file that explains the details of what files are included and also where any new downloaded or created content should go. I wasn't trying to make it more confusing just figured an explanation in a file manifest (like you said in your post) explaining the situation would suffice to answer this. Apparently my special ability of obfuscation overcame your resistance
