I have one simple question: as a novice with flex i don't
know how to determine that file is image so it can be displayed by
component Image. For example in Java if i set incorrect file to
ImageIcon i'll see that height and width for created image equal to
-1, so i'll know that data doesn't represent dysplayable content,
but in Flex the area occupied by Image component will be blank
without any hints. Is there any ability in Flex to know that file
is image (of course comparing its extension to *.jpeg, *.bmp etc.
