New Picture Upload Bug....

Ok this is what happened.. i wanted to upload a NEW picture.. so i tried.. and instead of replacing the old picture with the new one, it still displayed the old picture..
so i tried DELETING the picture.. then it was deleted.. and i now tried uploading the NEW one.. BUT to my surprise the picture was still THE OLD ONE.. how is this possible?....

I cant seem to upload a pic at all, everytime i try i get the error message, 'this is not a vaild .jpg file' or similar, even tho it is. :(

Ok..just below this thread was one that had what i was looking for, heh and all it was , was opera....opera seems to have a lots of probs with some pages.
Still love it tho :)
