[PHPRETRO] Backgrounds

We all know how old school hotels have died out but this is really serious for me because I get around 10+ online every single day and I want everyone to have a perfect experience of how Habbo really was back in the day or who people who really missed Habbo and who would really love to see bugs solved, this is for me also.
So, all I wanna know is how do you sort out the background bug? I place one background, that will work. If I place a second one to replace the first one it will not work after I have clicked 'Save Changes' this is a really small bug but do you know? If so please comment below and tell me how to fix this bug, thank you!

By the way if you would like to checkout my hotel click here.
Kind regards,
Chuck.
