i found another thing:
previously i created a folder name: /Banner N Header/dec 02.jpg
it has no problem viewing from front & back end.
now, i see my FTP folder change to: /BannerNHeader
it removed the words spacing, so my image can't locate properly. it is so confused, where i could make them sync, so my image location are correct with the server.
it seems, the server could not recognize the space & maybe big capital letter.
Desperately need help.
Thanks.
