I call the above function in onmouseover of a thumbnail.. which show the large image in new div..
it works properly in IE
but when i use firefox.. at first time it returns heigh 0, and give proper result when same function is called second time.. on every thumbnail.. first time is show o heigh on alert...
what's wrong with firefox?? (specially when the funtion is called first time )

what's wrong with firefox

Nothing. The image has to be loaded into the browser cache before the sizes can be read.
