girl i am also in the same dilemma my pictures had the white background too but let us not loose hope because on the advertisement they did not specify the background color and also as long as the pictures do not make you look like you are flying then we are okay
like '
ughostess' said if they see our potential a picture background will not prevent us from getting the invite
all the best and i hope to see you at the AD and keep smiling because that will be you greatest asset on that day
