Yeah I could have a word with him and see if he would make some alternatives so when the loaders done there can be a folder of sets of backgrounds. My 4 and possibly the one I had before I made these ones, was similar to pepperoni's but modified, and then a few other sets, main and config png's.
that way you can change to what you want by just selecting from the folder. In fact if this could be integrated, added to the todo list, where as mentioned bfore you could actually select backgrounds in the loader. Myabe it could be an option and it had the different names like Dark and Light for my ones and you just choose by pushing left and right in the options box and it saves it to config to select those proper pngs from the folder.
Actually just checked that thread and are you sure that wasn't just my background he modified, I don't recall who made the original, wasn't AppleBelly was it?
