But what is wrong with 'image.onload'?
It should take care of any timing problem?

Or, you could build the onload yourself, as, [if my stipulation that the 
measured width is either 0 or the true value is correct,] you could build a 
a module testing for this zero and repeating that after a small timeout till 
the value is nolonger zero.

WeLl, you would have to specify the engine you are talking about,
so the browesr type and version. And perhaps the O.S. core functions could 
be different.
