I am trying to add wallpapers to my TS7 and Controller. I can load the directories on my Mac and see the default wallpapers but when I try to add more wallpapers it gives me an error message. "cannot be copied because not enough room" I am following the exact size for each device. I also tried erasing a stock wallpaper (which was successful) and then adding my own. Same error. I then tried to add the stock wallpaper that I had erased. Same error. Am I missing something? Thanks in advance for any help.
