Thank you absolute! After changing the jpeg file extension from upper case to lower case, problem solved! Many thanks.
Got one more question, It's rather annoying that the Register screen having the privacy statement check box on the top of the screen, many user would forget to tick the box before they press the sumbit button. I once tried to have the box ticked as default, but 2 minute later I decide to undo it as it's unfair to assume the user agreeed to my pravicy statement and it maybe illegal. Since all other fields and radio buttons on the register page have a message box function telling user that they have to enter something or enter something valid once they click submit, however, for the privacy statement check box, the page will start loading then shows a warning message on the top of the screen. That was not a problem, the problem is all user input i.e. name address, phone number ... everything will be gone! I think is a bit strange comparing this to other websites. Have you got a solution regarding this?
To garethrooney, Hi mate. When I gone into admin and turned on SEO, all additional images were not wrapped correctly. Once I turned SEO off then they look fine again. I know is not a very good answer, but that is what happen to me. Good luck.
