Background upload problem

Since I tried to find an answer and reach ppl that could try to work this out and it hasn't helped at all, could anyone else tell me why on earth I haven't been able to upload a background that's less that two HUNDRED kb ever since April 10th, 2008??? It's really annoying, I treid to upload a bg many many times, it says it's updated but it isn't, the grapic doesn't show!!!!
